Can you build a tool to pick up a ping pong ball using only one hand?

: You’ll need to figure out a way to hold a sphere (a ball shape) in place so that it doesn’t roll off of your tool. Which materials are most useful?

 Can you create a tool with moving parts that lifts the ping pong ball? What else can your tool carry?

 Build a tool that can pick up a ping pong ball with one hand, without touching it directly.

 With the materials you have, what would you like to try? What sort of tool would be helpful?

 A prototype is like a first try – see if you can build what you imagined.

 Could you pick up the ball with your tool using only one hand? Did it roll away, or fall off/out of your creation?

 What other materials could you try? What shapes work well to grip the ping pong ball?

 Try making a claw with joints – you can do some research on articulated hand STEM challenges for inspiration!
