When coins pass through the opposite poles of magnets, currents are induced ending up putting a brake on rolling-down coins. Since different types of coins contain different kinds of metals and their masses differ, the force amount of brake put on different kinds of coins cause them to fall on different spots in the vending machines. Let’s try to understand this principle in vending machines or coin changers.

Check out the kind of information contained in daily-used QR code, create and print out your own QR code.

Place stop-motion dummies in an intended order. You would observe the motion of the dummies is perceived sometimes as consecutive motion, or stop motion or reverse motion depending on the intensity of LED strobe lights’ vibration. This experiment is to find scientific principles behind this phenomena, namely optical illusion and afterimage of vision.

Scientific Principles Optical Illusion and Afterimage/ Strobe Effect

Vestibular organs(semicircular canals), which control vision and balance, are responsible for the body’s balance system. If the information about something’s vision and balance is not identical, people get to feel motion sickness. Ride VR simulator to understand how motion sickness is caused when this happens.
