This is a very cool, simple science experiment and the only thing that you will need is a box of matches.

Step 1: Fusing The Match Heads
To do this, just light one of the matches and hold however many match heads you want to be fused together on the ground (you should probably do this outside) making sure that all the heads are touching and wait for every match head to be lit. Now you can blow them out.
