How to Make HOT Ice!

Making hot ice isn’t difficult, but if you don’t follow the steps correctly, your project will be messed up and you will have to start over. You want to get it right the first time because this experiment takes MASSIVE amounts of vinegar.

We looked at about 5 different recipes for hot ice and tried them all, but all of them failed except this one. We used about a gallon of vinegar before we finally got the experiment to work. We felt like real scientists having to work so hard to make something happen!

Wear gloves and eye protection when doing this experiment to keep safe.

We boiled our vinegar too hot, so our ice turned a bit yellow. That doesn’t affect results, but it does make it look less like ice.

Our crystals finally formed after boiling our fifth batch.

Rinsing the crystals with rubbing alcohol got rid of some of the yellow color (but not all).

Can you believe this started as six cups of vinegar?

You’ll want to be careful when moving the mixture from the refrigerator to where you plan to pour it out, because if you bump it too much, it could harden in the cup.

Let the kids pour out the vinegar mixture and watch it harden right before your eyes!
