Pen Launcher
I made this for 'Pen Wars' in my class.
Warning : Don't shoot at the vital organ !
What you needs : - 15 sheets paper of 12 cm × 17 cm
- Pen ( I just use the inside of the pen )
Roll the Paper
Roll the paper with the body of the pen
Gluing or Binding
Use Fox Glue for gluing ( you can use the other glue, but Fox Glue is better ) or Binding with rubber band
Testing
Put the inside of the pen on the rocket, take a long breath, then pull it in the launcher
