This neat little parlor trick using milk, food coloring, and dishwashing liquid will be perfect for my daughter’s birthday party. It’s probably a classic, but I’ve never seen it before. Don’t drink the results! -via Grow-A-Brain
OK, we tried this at the birthday party tonight. I used half and half, which is 5% fat. It worked perfectly! The colors roiled for a long time til they were perfectly blended, and continued to roil after it was hard to see it. The kids loved it! Princess even made me do it a second time so she could record video with her new camera. It's a bit too long and giggly to post, but she is going to send it to her science teacher.
I did this with my 8 and 10 year old boys after I watched the video. It worked and they thought it was the coolest thing ever! I scored some mega Mommy cool points with this! They want to show everyone at school.
