So im looking through my old science book and I come across a project. The project is to light a match....the catch is you cant use friction, flame, or a magnifying glass. Having never done this project I decided to try it...so far ive tried electrcity. I hooked some wires up to a 9volt and tried touching the match with both - and + but nothing happened. I thought it would ignite like those model rocket engines do...but nothing. Any ideas? |
50mw laser? |

Insert upright into post. Take 10/22 and from 25 yards, graze a bullet across the tip..... Turn on electric stove and touch tip of match to burner Start car and let heat up....Touch tip of match to exhaust manifold. Put in oven and turn on any temp above 451. Touch to hot light bulb. |

The trick is to use wire that can't handle the current from the 9v battery. If you use thick wire, it will pass the current without heating up the wire. Take some stranded copper wire, stripe it down and cut out a nice length of fine hair width strand. Wrap several turns of this around the match head. Now touch the ends to the 9v. Whoosh! |
| Scrape the side of a AA battery near the (-) end until the metal case is exposed. The metal case of an alkaline battery is +. (If you use a NiCad, the polarity is reversed.) Slice some cigarette pack liner paper (the paper/foil stuff) into strips 3/32"wide x 1-1/4" long. Fold those in half with the foil on the inside, and then seperate the strip enough to then touch one end to the negative end of the AA battery and the other end of the paper strip to the exposed battery case. It will heat/flare up enough to light a smoke... or fire up a match. Aren't inmates creative? Stay safe |
