Ping-Pong Ball Rollercoaster

I'm going to show you how to make a ping-pong ball rollercoaster. It works and it's easy to make.

1. 6 Paper plates

2. 2 Paper towel rolls

3. 1 Toilet paper roll

4. Tape

5. Scissors

6. Ping-Pong Ball

Get your paper plates and cut a hole in the middle in each one except one paper plate. Then, using your scissors cut all the way to the middle on one side in each one except the one you didn't cut a hole in. Next, tape the plates like in the 2nd picture and first tape 3 palets like that then tape 2 plates and that should leave the one you didn't cut. In the 3 paper plate spiral put the paper towel roll in the hole and if it doesn't fit try to cut the holes so the paper towel roll can fit. Then, in the 2 paper plate spiral put the paper towel roll in the hole and if it doesn't fit try to cut the holes so the paper towel roll can fit. Space both spirals enough so the ball can roll without getting stuck and then tape the spirals to the paper towel roll so it stays in place

Tape the three plate spiral to the plate you didn't cut. At the bottom of the 3 plate spiral there should be a spiral without a plate taped to it and when you see it get the toilet paper roll and tape it to it. Next, tape the toilet paper roll to the 2 plate spiral so the ball can go on it and make sure the bottom of the spiral goes to the very bottom plate so the ball can go there at very last spiral.

Put your ball on the top if the 3 plate spiral and let in go. If the ball stops the it's not steep enough or there isn't much space in between the spirals or it's stuck to the tape. If it stops at the toilet paper spiral then it's not in the right place or it's stuck to the tape. If the 3 plate spiral is leaning then it is not well taped to the plate at the very bottom. If the 2 plate spiral is leaning put something under it to keep it straight. These are some problems you may have but maybe there's more. If you don't have any problems then sit back and relax and goodbye.
