making a lava lamp

[twisted_screams]

My son has a project to make a working lava lamp for school its 80% of his grade. We settled on what google calls a poor mans lava lamp. It sounds pretty basic but finding the stuff to make it with is a pain in the butt. It takes mineral oil ( you can find it in some pharmacy's) 70%rubbing alcohol and 91% rubbing alcohol ( which turns out you have to get a pharmacy to order) and then there is food dye.. Today i sent my kids to the first store for food dye and they came home with the response *huh* you can dye food* the second store was Latino and thought they were asking for change for a ten ( makes note to ask Mr Birdy if food dye is Spanish for give me change for this money) and the Koren store offered my kids some kind of foot powder. I had to laugh when three different stores don't have any idea what in the hell food dye is hopefully after work ill be able to hunt some down some where.

70% Rubbing alcohol and 91% Rubbing alcohol is well above a 100%.

I have a different type of lava lamp that involves nitroglycerin and plastic explosive. Just drop it on a mountain and run, and bam. Instant lava. :D

I didn't think those items would be all that hard to find. Did you check Wegmans or some other grocery store for the food dye?

For Who its not a measurement of 91% and 70% its the type of alcohol that is supposed to be used.
I made the damn thing and had the mineral oil doing its whole looking like a bubble thing sat it on my mantel so the kid could take it to school tomorrow when all the sudden BAM the damn thing exploded into about a million pieces all i can figure is that some how it built up some kind of pressure or fumes or something so long story short i am writing a letter to the teacher telling her to forget it hes not doing the project if it may blow up ( and i followed the directions to the damn tee gotta love these school projects nowadays I just wish they would go back to the pop cycle sticks and glue

To me a poor mans lava lamp only involves me, my hand, and my penis.
