Click here for another. It's not as pretty, but has more balls. Change the number up top left, and click "play." You can mess with the balls as they're moving. Close ads and turn the sound on.
Here's a Newton's Cradle simulator with more explanation, and conditions to set, at myPhysicsLab.
And another cool pendulum thing, kind of a cross between the physics of music, and the art made by wrapping stringing across a pattern of nails on a board. Trippy hippy stuff. (And physics pattern stuff.)
There are homeschool science fairs. Anyone who doesn't know that probably should know. There are school-at-home families who make their kids do a science fair project. Unschoolers don't do that (though it's possible that there have been unschooled kids who have found out about those fairs and asked their parents please PLEASE to help them with a project and to buy them one of those folding display boards! Maybe. )

When I put that image and some questions about what parents thought about science, and whether such display boards and science fairs existec outside the U.S., there were lots of friendly, sensible answers, and one that led to some problems. I've preserved it without the name of the commenter.
Scientific method is touched on, and some other logic issues.
"Statistics"
Not actually useful statistics, but failed attempts to make geography and math prove one point or another. One is the entire population of the earth moving to Alaska, and the other is all the penguins in Antarctica being transported to Ireland, suddenly, it seems.
