Engineering Challenge

[rp181]

A while back I did a straw rocket thingy, and won by a far shot.

For the straw rocket, I folded the straw over. The judges let me go, but when it hit the opposite wall, they started throwing stupid "rules" at me, like it had to have fins (tiny pieces of tape) and clay (little blue smudge)

What type of straw rocket was it?

[starman]

Egg drop, newspaper bridges, wax paper boats were my thing....

[Marffy]

Thats pretty cool. did you guys just thro the planes yourself or was there some kind of launcher?

[Techie]

bridges, towers, egg drop, bottle rockets, we had so many competitions the past few years. Guess who won them all?

[deathbyDWV]

We threw them ourselves.

I'm in 9th grade now but I've never do e a toothpick bridge.
The only rules this year were size and under one pound. Also 50% of every one has to be showing. I might do the bridge in 11th grade cuz the rules change. Then it goes by efficiency. It's weight of bridge to weight held. I bet I'd win that.

we used popscicle sticks.
My bridge held several bricks and weights.

We made boats to hold weight as well.

Yep, they had a challenge there (it wasn't one you had to sign up for) to make a boat of aluminum foil. Then they dropped pennys in. One held 200. That was the most. It really didn't seem like much...
