In this video tutorial, viewers learn how to make a marker-canon. The materials required for this trick are: a marker, scissors, knife, thread, super glue and a balloon. Begin by cutting off the bottom and top parts of the marker, leaving just the tube. Then cut the balloon and glue one half on the bottom of the marker tube. Now cut a long piece of thread and wrap it around the bottom of the marker tube. To use it, place the ammo inside the top of the tube, pull back the elastic and release it.
