265/366: Pintember Soap

This is cool.

Easiest activity yet!

Ivory soap.  (Even old, rarely used bars work).

Only Ivory soap works for this.  When you put the soap in an operating microwave, the soap and trapped water absorb the microwave energy and heat up. Eventually the water turns to steam. Steam takes up much more volume than the equivalent quantity of liquid water, and this drives the expansion of the soap bar. In addition, the air in the trapped bubbles expands as it is heated, contributing to the expansion.


Cool, right?

This is what Big Boy thought of it:

It is an interesting texture.  Give it a try!  Put your bar on a microwavable plate, 2 minutes should be enough.   Have fun!   Here is the original post:
