Fred's World of Science: High Energy Discharges

| Navigation | [Apples] [N2 Laser, v4.0] [Fireball] [Zinc] [Research] [Main] [Exploding Apples] |
| The following picture is of a simple experiment. 2 grams
of 200 mesh
powdered zinc was laid out in a 2" long track, electrodes on either end of the track. Some 2kJ was discharged into the zinc powder, resulting in a large, impressive blast. Oxidized zinc is what is seen in the picture. The zinc that didn't rapidly oxidize was fused into a 2" long, charcoal looking brittle mess of zinc. |  |

A fireball in the lab... A film canister top is being filled with about 2cc of ethanol. |
 |
And then, we discharge. I believe that the spark vaporized the ethanol, which subsequently exploded in a large fireball. |
|
| Here's a few pictures of our N2 Laser, version 4. There
was a large
arcylic tube evacuated with two parallel electrodes. One was smooth, one was a hacksaw bade, to initiate plasma. We were not actually firing the laser in the following pictures, rather just using at as a pretty prop for photos. This was
ca September 1998. |

After an internal short, or something like that...
