Ping-pong bowling
단계
- 단계 1
Grab some bricks and ping-pong balls
Try and get a good stash of LEGO plates for making your rolling device.
- 단계 2
Make three goals
One small – with a gap just wide enough for a ping-pong ball. One medium – a bit wider. And one big – wide enough for a whole herd of ping-pong balls. We started with six studs for the small goal’s gap, eight for the medium and ten for the large.

Make a rolling device
Build a rail or track that you can roll your ping-pong ball down. Think long and flat with tall sides to keep the ping-pong ball on track. Test out your device as you’re building.

Take turns bowling your ping-pong balls
Use your rolling device to aim your ball at one of the goals. Choose your goal carefully. You get three points for the small goal, two points for the medium, and one point for the big. (For added mayhem, have everyone bowl at once.)

Upgrade your rolling device
Can you build a totally different – and totally crazy – device for getting your ping-pong ball moving?
