Yes, you can weigh your car by figuring out your wheel's tire pressure combined with the "tire's footprint." You'll need someone with a car, driver's license, and safety in mind.

This trick from Exploratorium physicist Paul Doherty lets you add together the bounces of two balls and send one ball flying.

This is an activity about reaction times. Just how quickly must an NHL goalie respond to save a shot, and how does your reaction time compare?

Create a simple dual pendulum and get them to swing in identical ways. This is a simple, low cost, activity produced by the Exploratorium.

In this activity, learners explore electronics and motion by making a Scribbling Machine, a motorized contraption that moves in unusual ways and leaves a mark to trace its path.

In this activity, learners can observe chaotic motion. A magnet tied to a piece of string makes a pendulum, which swings over three sets of fixed magnets.

In this activity, learners create and experiment with wind tubes. These tubes are a playful and inventive way to explore the effect that moving air has on objects.

In this activity, learners will build a ball run contraption.

Cardboard Automata are a playful way to explore simple machine elements while creating a mechanical sculpture.

A simple, yet fun activity that lets learners find the center of balance of a ruler (or any long thin object). Developed by the Exploratorium and no assembly needed.
