The best thing to use is whole milk because it has the most fat in it. You add a few drops of food coloring. Use all the colors that you want to see swirl. This is red, this is blue, this is yellow, and this is green. You want to get the color all around so it looks cooler. Last, you add a tiny drop of liquid soap. You really don't want to add too much. Just dip it into the soap and let it drip into the milk. This is where the magic happens. Abracadabra. The colors are swirling around like crazy. It's like liquid tie-dye. The science is that the soap is chasing the fat in the milk and as it chases the fat, it swirls the colors. Important tip. Do not stir the milk. If you mix it up, it stops working. Abracadabra, you've got magic milk. Make raisins dance. This is what you need to make dancing raisins. You need any type of clear fizzy drink, a glass, and you need raisins. First you're going to open the bottle and you're going to put it halfway into the glass. See, liquid that's bubbly is called carbonated. Carbonated means that a certain type of gas was pushed into the liquid. As the gas comes out, it makes bubbles that flow up to the top. After that, you take your two smallest raisins that you can find and you can drop them into your fizzy drink. The bubbles attach themselves to the raisins and float it up to the surface. When the bubbles pop, the raisins sink back down to the bottom. They're going up and down. They're floating at the surface and I'm waiting for them to pop. I made background so my raisins can dance on the stage. Rockets. Or you can dance like a raisin.
