Remember the eggdrop puzzle that we had last year? We were supposed to build a package that could protect an egg from smashing when being dropped three floors. It was fun -- but it could be made less nerve-wrecking by not counting it as part of the exam! This year also had a physics puzzle as part of the exam, but it was to build a bridge

for the egg one, we werent allowed tape and all that elastic stuff to hold the egg rite. we could only use toothpicks and nth else?

and it wasn't that difficult, I got 10/10 for it... really helped with my barely there physics A.

Toothpicks were a lot harder. In retrospect, the main problems is figuring how get the toothpicks to stay rigid (answer: lots of triangles) and creating a bendy/springy part. Most solutions either involved using a bendable joint (via a more elastic glue like silicone) or by having a certain toothpick segment be bendable.
The solution I liked best was frankchn's creation. Frank decided that the upwards deccelerating force on the egg had best be *frictional* rather than *normal*, so he built a huuuge upside-down four-sided pyramid with very steep sides and put the egg in it. It worked.
