If you and/or your kids like photography as much as we do, you'll appreciate these! http://www.liquidsculpture.com/
Here's a description of the site from Mercola.com:
"Liquid Sculpture is a wonderful collection of high-speed photos of pouring and splashing liquids in motion. The pictures are really striking, especially the gimmick shots done with viscous creams and colored liquids.
What you see here and on his site are high-resolution images of liquids colliding with one another, captured with high-speed flash photography.
The artist creates his range of shapes by varying the speed, position, and size of the drops and controlling how they fall, along with the flash. Their simplicity and beauty are truly amazing."
