I was told to use skim milk, that whole milk wouldn't work, but then I read that the higher the fat content, the better. So I don't know, now. Skim worked fine, but maybe we'll try half and half or something the next time.

Warning! Science content: The soap reduces the surface tension of the milk by dissolving the fat in the milk, allowing the food coloring to sink into the milk, but then rising again in a different part of the milk.

  • i did this in my science class, but i used half anf half. i also put the soap on the end of a match,and then stuck it in the middle. it worked sooooooo good, and i tried it myself,and it didnt work at all :( what a fail.

  • To get even BETTER results, pour the food coloring all in one spot.. It looks amazing :)

  • lol it looks like hippie juice =D

  • nice video man this was a school project that i had to work on but it didnt work out right because we were told to use non-fat milk but now i saw that it needs to have fat content and it worked out perfectly so thanks

  • Have you tried this same experiment, only you drop the food coloring closer together, and instead of just dropping the soap in the middle of the plate, you take a q-tip and dip it into the dishsoap and then push the q-tip into the middle of the color "cirlces" and it makes a very cool effect.

  • @OreoKat133 Thank you! He *is* cute!

  • @imagineermatt thank you soooooo much!!!!!!!i tried it and it worked awesome! and thank goodness whew
