Soap making, a video by photographer David Brooks, features 16th generation soapmaker Kerri Mixon and her small business making organic, vegan, and handmade natural soaps in San Diego, California.

There’s a lot of chemistry to soap, and a lot of ways to make it. For a simple craft approach with younger kids (like mine), we found two vegetable glycerin soap DIYs here and here…

Did you know that liquids are stackable? It’s possible because liquids can have different densities: some are thicker/heavier while others are thinner/more light. 

From YouTuber Brusspup, watch how to make your own Liquid Stacking experiment: 

You’ll need:
an empty bottle (with a lid)
a measuring cup
dark corn syrup
dish washing liquid
water (add food coloring)
vegetable oil
rubbing alcohol (add food coloring)

And you can add two more layers if you have some honey (most dense) and lamp oil (least dense).

The video notes recommend not turning it over too much for fear of the colors getting muddied, but isn’t seeing what happens when they mix really the second half of the fun? The kid should do this!

World champion sand sculptor JOOheng Tan was recently asked by ad agency Lowe in Singapore to help create these impressive backdrops for an OMO washing detergent ad campaign. In an age when something like this could have been created digitally, they asked Tan to physically build three 18-ton sand sculptures to be used as backdrops in ads encouraging kids to get dirty.

This experiment was featured a few months ago in a video that had a variety of DIY science tricks. But it’s such a fun and easy activity to do that it bears repeating: Get some milk, dish soap, food coloring, a plate, and then wait for the oooos, aaahs and whoaaaas.
