Do It Yourself Suspension Lava Lamp

Here is a "groovy" way to study the properties of a suspension which you can do with some common household products. With water, oil, alka seltzer, food coloring, and an empty bottle, you can make your very own heterogeneous mixture suspension which very much resembles a lava lamp. Far out, man!

can u make it with something besides alki seltzer

[MrLundScience]

Anything that will produce a gas when mixed with water should do the trick. We did run out of Alka-Seltzer one year and used denture cleaners instead. We had nearly the same results, but also, over the period of 3 days, the food coloring was bleached by the cleaners. It went from dark blue to lighter and lighter shades, eventually to a sky blue.

how long does it last for

[MrLundScience]

The easiest answer is that it lasts for the same amount of time that your alkaseltzer will last. (Approximately 1-2 minutes.) To be more specific, the duration will be longer or shorter depending upon how much alkaseltzer you place in it. You can get more than one use out of it, but eventually your water will be saturated, and not able to dissolve more of the selzter. For this lava lamp, the idea that "less is more" applies. Putting in too many tablets at once will ruin the effect.
