Tell something about your fourteenth year. In my fourteenth year I learned how to make tiny rockets using matches and aluminum foil.
On a similar vein. I think i was 13, maybe 14 when i learned how to...
...close up one end of a copper tube and drill a small hole in it. Break a banger (firecracker) and pour the gunpowder into the tube. Stuff the tube with a bit of toilet paper then drop a sawn of bolt (just a little less than the inside diameter of the tube) into the tube and pack it all down with a bit more toilet paper. Stick the banger fuse into the hole and secure it with a bit of blutak. Wedge the whole device somewhere, light blue touch paper and run like hell to the side of the tube.
Whatever you do not run in front or behind.
