quantum particles

Quantum particles are tiny, invisible particles that make up everything in our universe. They are so small that you need special instruments to be able to see them. Quantum particles have special powers: they can be in two or more places at the same time, they can be in two or more different forms at the same time, and they can move really fast! They also do things that don't usually happen in everyday life, like passing through solid objects and disappearing.
