Not only is this a showstopper for the kids this 4th of July weekend, it’s a built-in science lesson! Mama, how do the liquids stay separate? they’ll ask. In your best Bill Nye the Science Guy voice, tell them the secret is in the sugar! The drink separates by keeping the drink with the highest sugar content on the bottom, and the least on top. So it’s super important to have a full-sugar red drink on the bottom (Hawaiian punch, Grenadine) and medium-sugar blue drink in the middle (Gatorade G2 works great, just don’t get the sugar-free kind). On the top you want a sugar free clear drink like diet Sprite or 7up.
Make sure to add ice with each layer; it helps with the separation. And if you’re supermom, make star-shaped ice cubes!!
