Making Newton’s Cradles

newtons-cradleWe continue our adventures with physics. We have been particularly focused on Newton. Each of the kids made a Newton’s Cradle using an old box, a box cutter, ping pong balls, sharpies, packaging tape, and fishing line. The project went really well. I have done this project with kids in the past. I think the heavier, bouncy rubber balls work better than ping pong balls. I would recommend using them instead.
