It was soap and bubble time for school last week. Here are some of our projects.
If you are bored and randomly have a bar of ivory soap, microwave it. This was a big hit with Mr. C. PB was having after-nap-angst.

My brother in law talks about a slurry they use in his construction job. This is our version. It is soap, and I’m pretty such it looks and acts like nothing they are doing.

We also tried giant bubbles that only partway worked. (Dry climate? Hard water?) They only partway worked, so I don’t have pictures.
