Here is a origional rocket that I made, and ill be telling YOU how to make one to! Have fun!
All you need: small pen, button (two holes), hair grip, spring (this should be wide enough so it dosn’t slide inside your pen.)
1)First of, take apart you small pen so you only have the pointy end and tube.
2)Secondly, slide your button (which should have TWO holes!) into your hair grip.
3)Next, slide your spring through the bumpy side of the hair pin. this will stop it flying out later.
4)Lastly, slide your hollow pen onto both sides of the hair grip. Hold your button on the bottom, push down your pen….WHOOSH!! Theres your rocket-have fun!
