for a tougher assignement, try building a beam using only balsa wood and glue capable of spanning a 12" void and supporting maximum weight at it's midpoint.
my entry supported over 160 pounds before failing. And oddly enough, had I not listened to my grad assistants advice, it would have done more.
I never got to do the egg experiment.
But for the bridge experiment, I got to do that one.
My class however, had to build a bridge within a certain budget using tooth picks and wood glue. My teacher assigned value to each bundle of tooth picks, and each little cup of glue we used. The bridge had to be supported by a flat piece of wood simulating the ground, and there was a hole in the middle of the "ground" to hang the weight through.
My bridge won, and I got to engineering stage a little late. I believe I could of built an even stronger bridge, but I will never know, we still where the strongest for the class. This was 7th grade for that project.
