The swift strike of a match on July 4 typically precedes sky-high spectacles. But matches themselves can be fireworks. When ignited, the bulb of fuel on a match’s tip combusts into space-hogging gases. By containing the gas in aluminum foil and directing it downward, you can create a miniature missile. Follow these steps to become a rocket scientist in your own driveway.
- Sewing pin or needle
- Paper clips
- Aluminum foil
1. Bend a paper clip into a 45-degree angle. Presto! You have a launch pad.
2. Lay a pin along a matchstick so that the sharp tip touches the match head. Wrap the head with a piece of aluminum foil, and gently crease the foil around the pin (avoid tears and holes).
3. Remove the pin. This leaves a hollow channel that will direct gas downward, so it can act as propellant.
4. Rest the match on the launch pad, hold a small flame under the foil-wrapped match head, and start your countdown.
Time: 10 minutes
Cost: About $3
WARNING: Kids, you need adult supervision. Launch only outside while wearing eye protection, and mind your aim (matches were designed to start fires).
