You’ve already seen the way a no-flinch pendulum works, so now we are changing it up. This contraption is host to many pendulums next to each other but not touching. When you raise them up and let them go all at once, you can see something truly mesmerizing. They will all start to fall at

You can use slinkies to demonstrate all things waves! Start with the basics: wavelength, amplitude and frequency. Once you’ve got those down, then you can play around with some things that are a bit more complicated like wave type, standing waves, and superposition. Longitudinal waves, like sound waves, expand and compress as they travel

Waves are everywhere! Electromagnetic waves traverse the vacuum of space. Gravitational waves ripple spacetime itself. Mechanical waves propagate energy through air, water, and other media. Sound is a great example of a mechanical wave. Vibrating molecules disturb their neighbors, which disturb their neighbors, and so on. The individual units don’t move far, but the energy

Woah! What just happened? To try and understand it, lets take a closer look at the Microwave. These are often thought of as magic food reheating boxes, but they are actually quite interesting! Microwave ovens heat food by bombarding it with electromagnetic radiation, also known as light. Unlike the light most of us think of
