Order a piezoelectric lighter and place it in the two side holes. Then, secure it with hot melt glue to ensure it won't slip. Finally, spray ethanol into the chamber of the alcohol injector, and you'll hear a loud "pop"!

Warning

Don't put anything into the "barrel" of the launcher. Doing so could result in the object being ejected at a deadly speed.

Warning again

This is as dangerous as firecrackers.Point the nozzle away from youThe direction of anyone, especially when you think the nozzle might be clogged.

This is my first time to get in touch with pyrotechnics
