colloidal suspension

2006

Yep, a lava lamp. I always wanted to make one with my own mixture, so I found a recipe on the net somewhere and tried it out. It took me about two tries to get the mixture right, and I think it turned out well. I forget the exact mixture, but I used a mix of alcohol (main ingredient), beeswax (the solid melty stuff), and some turpentine. I think there is 65 watt bulb in the coffee can.

This thing gets hot. Make sure the glass is well tempered. I tried it with a large pickle jar and it shattered from the heat, dripping alcohol and wax all over the bulb, shorting my wiring. Whoops.
