your red water and then with the yellow water. At this point, you should have a miniature, muddled-looking rainbow of color in your bottle, as the water floats on top of the color below it. (See Fig. 2.) If, however, you’re having trouble with this, try tinkering with the amount of sugar you use. More sugar will create denser liquid, so try messing with the amounts to make a rainbow stack to your liking.

2. Option #2: Bleach Lava Lamp: Mix red food dye with the corn syrup and pour into the bottle.

Then pour the oil into the bottle on top of your syrup. The oil should float on top of the corn syrup, because it’s less dense. Now add the blue food dye to the water in your measuring cup.

Pour the water on top of the oil in your bottle and give it a few minutes to settle. It will actually sink below the oil and rest atop the corn syrup, creating a middle blue level. Once the water has settled, you should have three distinct layers of liquid at this point. The bottom should be red, the middle should be blue, and the top layer, the oil, should be clearish. Now pour in the bleach and watch what happens as the bleach eats away at the coloring’especially to the blue portion of your bottle. (See Fig. 1.) It takes only a few seconds for chemical reactions to occur, so keep observing as the blue layer completely disappears. I always think this experiment resembles a nifty Lava Lamp.

3. Option #3: Sweet, Delicious Density Treat: First things first. Fill your glass with ice. And when I say fill, I mean fill! Pour just enough red fruit punch or cranberry juice to create a bottom layer in your glass. Don’t fill up to halfway. Now, very, very slowly, pour in your blue Gatorade over the ice. You should notice the blue layer appears to float atop the red. Wait a tiny bit for things to settle. Now take your clear diet soda or sparkling water and pour super slowly over the ice. It should float at the top. (See Fig. 5.) Enjoy your red, white, and blue sugar buzz!
