Under water igniters by The Jolly Roger
|
|
|
|
Materials needed:
|
|
|
|
-Pack of 10 silicon diodes (available at Radio Shack. you will
|
|
know you got the right ones if they are very, very small glass
|
|
objects!)
|
|
-Pack of matches
|
|
-1 candle
|
|
|
|
Procedure:
|
|
|
|
- Light the candle and allow a pool of molten wax to form in the
|
|
top.
|
|
|
|
- Take a single match and hold the glass part of a single diode
|
|
against the head. Bend the diode pins around the matchhead so that
|
|
one wraps in an upward direction and thensticks out to the side.
|
|
Do the same with the other wire, but in a downward direction. The
|
|
diodes should now be hugging the matchhead, but its wires MUST NOT
|
|
TOUCH EACH OTHER!
|
|
|
|
- Dip the matchhead in wax to give it a water-proof coat. These
|
|
work underwater
|
|
|
|
- repeat to make as many as you want
|
|
|
|
How to use them:
|
|
|
|
When these little dudes are hooked across a 6v battery, the diode
|
|
reaches what is called breakdown voltage. When most electrical
|
|
components reach this voltage, they usually produce great amounts
|
|
of heat and light, while quickly melting into a little blob. This
|
|
heat is enough to ignite a matchhead. These are recommended for
|
|
use underwater, where most other igniters refuse to work. ENJOY!
