Fourth Meeting: Egg Launch

On Friday, November 30, we began our third annual egg launch contest. We are now divided into three groups, and from what I've seen we all made good progress. (I hear Peter's group has already started testing!) We'll try to finish up and actually get them launched next meeting.

Normally I say "video coming soon" or whatever. This time I won't bother. Frankly, there's not a whole lot to report....... yet. :)

Third Meeting: Kid Pix, Potato Rocket and Target

We started off the meeting with a healthy dose of Kid Pix. Once it became clear that we wouldn't get anything done for at least 20 minutes, I felt bad and let everyone go. But a select few stayed behind, and were rewarded for their patience. Willy stuck a rocket engine in a potato, and we took a few shots at the trusty old target--which, by the way, got a nice shout-out during the Cum Laude assembly the other day. :) Video coming soon.

UPDATE Feb. 9: OK, so the video probably isn't coming soon, but you can spot a quick clip of this meeting in the video montage over at The Beaver Reader.

Second Meeting: Nocka Rockets

Our dear onetime member Andrew Nocka may have left us for the UK, but his spirit lives on in the noble tradition of Nocka Rockets. Today we fired a few off, including a sort of corkscrew one and one with wings. Plus we ate cake. :)

First Meeting: Dry Ice and Potato Gun

We held our first meeting of this year on October 5, and I think it went pretty well. We played with dry ice and the potato gun. I've posted a video recap below.

One thing that we're aware of is that there was quite a bit of waiting, and we didn't have a chance for everyone in the club to really get involved. That's a hard thing to do with forty people, which is why we may experiment with breaking into multiple groups at our next meeting.

If anyone has any other comments, feel free to email Peter, Vivek, or me, or leave a comment on this post.

I know I had a lot of fun, and we look forward to seeing you again this Friday! We'll be playing with rockets, potato guns (bulding our own!!), and using magical chemistry skills unlike the world has ever seen, making silly putty. :)

Year 3 Begins

On Friday we announced the third year of the Beaver Science and Engineering Club. Unfortunately, Vivek could not be present, but at the last minute he beamed us this transmission from space:

"Dear Students of Beaver Country Day School,

"I am sorry I was unable to partake in this ceremonial gathering to commemorate the 3rd annual BSEC initiation, for I too am partaking in a ceremony of galactic proportions. Yes... that's right...I'm on the moon--that glowing white object you see in the sky every night. I would have come back, but... it would seem that upon arrival of this dusty, mountainous abyss of moon world that my space ship found its way deep, deep, deep into a giant cavity on the moon's surface.

"In other words, I got stuck in a crater.

"I give my sincerest apologies, and I... [radio cut off] ...Great Oz! They have eyes... red eyes... and tentacles... Mr. Adjout, help me!"

We wish the best of luck to Vivek and his crew.

On a happier note, this year we had a record 36 sign-ups, plus the three co-presidents and two faculty advisors for a grand total of 41 members. Our first meeting will be Friday, October 5. Hope to see you all there!

Well, the last few meetings of last spring will remain a mystery for now--but in the mean time, here's a fun video I just found:

Thirteenth, Fourteenth, Fifteenth, and Sixteenth Meeting Recaps

Thirteenth Meeting (April 20, 2007)

Ms. Nickerson and I ran clubs alone, since Peter and Vivek were off getting tuxedos fitted.

We made speakers out of wire and magnets, using a borrowed iPod as a sound source, and some other people tried to make electric motors. And some of us just had fun standing donut magnets up on edge on the table and rolling others around, making the stood-up ones spin nicely.

In our last meeting, one club member had conceived of an entirely new class of rocket: the Nocka Rocket, a.k.a. a hollow tinfoil tube with a pinched-off nose and a rocket jammed inside. This meeting, we actually went through with it. First we used a C-engine, and launched it out of the PVC launch tube. I didn’t even see the launch, ‘cause I was running through the play structure to get to Nocka and help him with the feisty igniter when he got it to work. But I saw it in mid-air! It spun some, dove, “pop”ed and smoked.

Then we went back inside and did another one, only with a D engine instead. This one I did see. I launched it (again from the PVC tube), it spun, it dove, it exploded with a nice burst of flame. The end, time for lunch.

Fourteenth Meeting (April 27, 2007)

Finally, we build bridges! Or try, anyway. In truth, after we split up into two groups, we never got far beyond the planning phase. We intended to continue in the next meeting, but we ended up having to take a break because of club member absences and such.

Fifteenth Meeting (May 4, 2007)

Hey, May the Fourth be with you!

We prepared three rockets. One was a long, thin, sleek black thing that Brendan found in The Closet. The second was a classic Nocka Rocket, only with a special plastic Charzard nose cone (which we lost). The third was a glider rocket that Brendan found and, with help, assembled. The first went off nicely, like so:


Video: BSEC 06-07: 15th Meeting: Rocket Launch

The second did what our made-from-scratch rockets normally do: launch, spin, nose-dive, explode. And the third we didn't have a chance to launch. That'll have to wait until another meeting.

Other than that? Umm, well, I do think I'm forgetting something, but I don't know what. Oh, we had Tootsie Pops, I think. But no, there was something else...

Sixteenth Meeting (May 11, 2007)

This Friday was a special schedule day, thanks to it being the Seniors' last day. (Congratulations to them, by the way!) As such, we had only about half the time we usually have--and half the attendance, too. We played briefly with LEGO MindStorms robots, mainly having them smash into each other so wee could see which one was stronger. It's fun to watch the wheels skitter about when they've been knocked off but remain wired to the control box.

Aside from that, we continued preparing our second glider rocket of the year.

Tenth, Eleventh, and Twelfth Meeting Recaps

We're coming out of somewhat of a lull thanks to four missed meetings (due to lack of school) and a general lack of activity. But fear not for the future of the club! Next week we're doing bridge-building and more. In the mean time, a recap of what's been happening since the last blog update more than a month ago:

Tenth Meeting (March 9, 2007)

We begin our egg launch project with what amounted to a planning meeting.

Eleventh Meeting (March 16, 2007)

We successfully launched an egg and returned it unharmed! Woohoo! We'll have cameraphone video at some point if we can get it from Willy...

Twelfth Meeting (April 13, 2007)

This meeting was for all intents and purposes called off, although we did half-heartedly attempt to make a slingshot.

Ninth Meeting: 8 Flips, Looking to the Future

We had our ninth meeting last Friday. We learned a bit about electricity from Peter, shocked ourselves (literally), and launched two rockets. The first was a stunning success, a.k.a. didn't catch fire and survived the whole flight. It shot up and deployed two little gliders, which we never found. But the main body survived! We haven't done that in quite a while!

And the second one... well, let's let it speak for itself. :)


Video: BSEC 06-07 - Flip Clip

More video coming soon, if I can figure out how to free up some space on my computer. (Wanna guess how much I have? Try 895 MB. We started out with 148 GB. That's digital video for ya.)

Looking to the Future

We'll looking at meeting every week from now on, starting... when? Next Friday? Let us know whether you're free during A Block.

Oh, and we're also actually starting our egg launch contest and possibly bridge-building.

As always, we welcome (solicit, even!) your feedback and ideas.

Eigth Meeting: Uhhh, you call *that* a meeting?

Ms. Nickerson was out today, so we couldn't really do that much today. We tried to make a hydrogen fuel cell car (from a kit) but for some reason it didn't work. At least now we have a handy-dandy little hydrogen generator (and solar panel too, though we didn't use that today).

We had some fun with a little static-electricity thing at least.

Next meeting, two weeks from now, will be better, I hope--we're starting a new egg launch contest! Whichever group gets their egg the highest (by any means) and returns it to the ground unharmed, wins. We're not allowed on the roof, though...

We also want to make Pikashoes, like so:

- The Original
- The Variant

Oh, and Vivek skipped. ;)

Video coming soon, though there's not much to see.

Seventh Meeting: Music, Dry Ice, and Rockets

Today we had our seventh BSEC meeting of the year. At the start, Ms. Nickerson had set up some music-related booths for us, including a rather nifty lollipop thingy. Next we somehow acquired some dry ice--I'm still not sure how--and blew up another bottle. Kind of. It only blew up once Ms. Nickerson tried to defuse it, naturally. The next bottle was a total dud.

By that time we had pulled out the rocketry stuff and were plotting two launches. The first would finally make use of Vivek's X-Wing that had been sitting in the closet for 1 1/2 years; the second would make use of, umm, some cardboard and tape and all the rocket engines we could find. (That only means four, alas.)

The X-Wing performed beautifully, right up until, uh, the point at which it nose-dived into the ground. Parachute? Yeah, we had a parachute. Problem is, it deployed about a yard above the ground... and it had a hole. Or two. Not much of a help.

Of course, we'd have been crazy to bother with a parachute on our other project: a cardboard tube with two cardboard wings held together with a little masking tape. (Far more sophisticated than our "rocket javelin" from last time, you see.) The nose-cone, though, was decidedly less sophisticated. At first we had a weight in there, to make it less tail-heavy, but at the last moment ripped it out. (That had grave consequences later on.)

So on that launch the rocket went up like it was supposed to, but then twirled and twisted and dove straight at the crowd of observers. Several people dove to the ground; a couple actually tripped over each other. I'm amazed nobody got burnt. Luckily, the body tube soon detached and left the crowd alone, instead landing right next to the launch pad. A few seconds passed, and then the next stage activated. Only, our pitiful replacement for the weighted nose cone -- aka a bit of tape -- didn't hold. The remaining rockets shot out the front of the tube and streaked into the air... and then landed in the pool.

Interesting experience. Video embedded below:

Sixth Meeting: Rocket Javelin

Compared to our Fifth Meeting--when we made dry ice bombs, burned random things, fired the potato gun, smashed a PC monitor to bits, and launched a four-stage rocket car--this meeting was downright boring. But it was fun, especially towards the end. :D

We started out with the intent of making circuits and, ultimately, a Rube Goldberg-esque contraption that would launch a rocket. But we skipped most of that. :)

We wanted to launch a rocket out of the potato gun. There would be very little point, except that it would be, uh, kinda a 'rocket laucher' of sorts. To fit down the barrel we couldn't use a rocket with fins, so we made one from scratch. It was an extremely complicated design: a cardboard tube, a makeshift paper nose, and a D engine stuffed up the back and secured with masking tape. We put a few party poppers in, in the hope that they would, y'know, pop. Oh, and I snuck a little bonus surprise in there... more on that later.

We tried using the potato gun, but it was virtually impossible to attack the leads to the rocket. In the mean time we amused ourselves with some silly string, which ultimately ended up All. Over. The field. We had initially tried dropping the rocket down and then reaching through the hole in the chamber, but it was too cramped for such a delicate operation. Next we tried threading the wire through the barrel and holding the rocket in place, just poking out the end. We were going to attach it with some of the copious silly string lying around until I remembered that we had tape inside.

On that attempt, though, one of the leads had come disconnected. Awwww.

People were getting bored, so we just put the "rocket javelin" it on top of a chair and launched it. Oh boy was that interesting. After circling several times, bouncing off the ground, and coming to a rest facing the opposite direction from the way it had been launched, people decided it was safe to approach. Willy set off at a sprint.

Here's where my surprise comes in. You see, I had decided that it would be more interesting if there was a second engine inside. And I kinda forgot to tell anyone.

So at this point the rocket shot off again. The second engine was much smaller, so it just kinda skittered across the ground. But I sure am glad no one had picked it up.

Oh, and then it caught on fire.

See for yourself:
