What happens when you put a bar of Ivory soap in the microwave? Well, because of the high volume of air whipped into a bar of Ivory soap, when the soap is heated, in a matter of seconds, it seemingly bursts to life, and rapidly expands into a huge, white, fluffy, cloud.
The Ivory Soap experiment is probably one of my favorite science experiments for kids because it’s so quick and easy, and it yields such fascinating results. There’s almost no prep required, and you don’t need any fancy supplies. All that’s required is a bar of Ivory (and it needs to be Ivory brand soap) and a microwave oven.
1. Ivory Soap Bar
2. Microwaveable Dinner Plate
1. Place your Ivory on a microwaveable plate
2. Put your soap in the microwave
3. Run microwave on high for 1-2 minutes. Today I set my microwave for 1:30. You can’t really overcook your Ivory, but it will reach a point where it stops expanding.
