Spaghetti bridge question...?

Question

I'm building a bridge for Physics I out of #8 spaghetti and Elmer's glue (the only allowed materials). Why was it suggested to me that I dry glued spaghetti with a hairdryer before it dries? What does that do as opposed to just glueing and letting it dry naturally?

Answer 1

The glue will soften the spaghetti and it will sag and become loose or wavy in places you don't want it to.

Also, heat will help the starches in the spagthetti meld with the glue, to make a better/stronger join.
