Pouring molten Aluminum into a Pumpkin (cooled with liquid nitrogen!!!)
The inside of a pumpkin has a pretty interesting geometry. I had the idea to cast the inside to see what it looks like, but the inside of the pumpkin is very fragile and the 1000 degree aluminum pretty much destroys it as soon as it...

Statics Formula Sheet
Static Equilibrium: F = ma = 0 (for static objects that aren't accelerating M = I_G alpha = 0 (for static objects that don't have an angular acceleration). Notice that moments can also be written as a vector using M = r x F. Note that...
