Physics: Right-Hand-Rule

This is in the shape of a hand to help students use and learn how to use their own hand for determining the force on a charged particle travelling in a magnetic field.
Currently it is only a basic 5 minute piece of work in Tinkercad, i hope to do better in future. I could not think of a better way to represent force coming out of the hand. Any suggestions or remixes is greatly appreciated.

Addition: i added a Left-hand-rule as well. Because I know some people prefer thinking of it that way.
