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.

This is a cool video. Is it real? I would love to show this to my Brownie Troop. Has anyone really tried this?

2% didn't work either

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.

Some people just need to lighten up already.. Sheesh! I thought this was very neat and if kids wouldn't think its cool then they are far too gone already!

Reminds me of one of those lava lamps, the way it moves.

That was pretty cool. I'm going to wait until someone is tripping out to show them.

Come on, kids, drink the milk. Everybody else is doing it.

This is the coolest thing ever in the history of cool things.

You're right su.wei, the dishwater liquid has molecules with an hydrophilic side and a lipophilic side (with anionic thing too, to allow the water to spread out else it would be in drops shape).

So the fat is stuck to the lipophilic side and the water to the hydrophilic side (that's why it cleans your dishes else water and fat don't mix together).

So, fatter the milk is (which is basically a mix between saturated fat, water, sugar - lactose - and casein - a protein -. the K-casein allows the mixing to be stable as an emulsion) and more reactive the mixing would be.

(forgive my english language)

i imagine that whole milk would be best. as the effect is from the fats interacting with the soap. hydrophobic and hydrophilic interactions of some sort?

Would this work with organic soy?

tried it with 1% milk and it didn't work. Do you think it needs higher fat content?

That's an awesome trick! Any idea how it works, tho? I don't understand why dish liquid would create such a reaction in milk.

whole, 2%, or skim?

i think it's TOTALLY appropriate for a children's bday party AND i predict that they will LOVE it. don't underestimate kids intelligence by thinking they'll drink it. likewise, don't overestimate the simple things that children will enjoy.

@Slapster - I dunno, I babysit a couple of kids who are 5 and 10, and "modern children" or not, they're still mighty impressed with much the same things I was impressed with when -I- was a kid - paper airplanes, Legos, cool little science tricks and what have you ... I think they'd both be quite impressed with this, too - the classics never fail!

I do remember this one on Mr.Wizard. Its better to use a larger pan. I think Mr.Wizard used a cookie sheet with tall sides..

> Put the soap on the tip of your finger then dip it in
> the milk.

Even better... Take one of those striped drinking straws, put the soap all around the end, and dip it in the milk. The white and colored plastic parts have different properties, so you get a star-shaped explosion effect.

How long will that hold a modern child's attention? I bet it would go over bigger with the "experimental" college crowd. Well, at least it would have back when I was in that crowd!

She's eleven, and her friends are twelve. They won't be tempted to drink it.

If it involves mixing milk and detergent, it's not appropriate for a children's birthday party.
