Can you create a slingshot that will knock down a human tower?

On Thursday, March 21 kid’s ages 9 to 14 years of age are invited to Puyallup’s public library to give it a try. Use your powers of scientific experimentation to build a slingshot that can topple a people-sized tower. It’s time to make Angry Birds your way- don's miss out, the fun starts at 4 pm.
