Science Buddies: "Ask an Expert"

I was wanting to find a way of incorporating kinetic energy and art. Would a Newton's Cradle still work if it had wet paint on the balls?

Newton's Cradle should still work with wet paint on the balls. The energy from the first ball will still be transferred through the middle balls to the last ball on the other side, causing it to fly up. The only problem that may occur is the paint causing the balls to stick together. To prevent this from happening, make sure to thin down your paint as much as possible without taking away its color.
