Great for rolling the paper into tubes when making rockets!
We designed this roller with a slightly larger diameter then the launch rod which makes the rocket an optimal size allowing it to slide easily off the launcher with minimal air loss or friction.
We also highly recommend it when building our missiles. It will help you get the colored edges lined up correctly.
Colors may not be the same as pictured.
- Helps insure that each tube is the correct diameter
- Rockets made using the roller slide easily off the launch rod with minimal air loss making them go higher.
- Discounted price for buying in bulk
- Good for groups of 10 - 20
