    • Mark and make half-cuts near the ends of the strip on opposite sides

    • The distance of half cuts from the ends should be equal

    • Fold the ends and lock them by passing the cuts through each other

    • Do not crease the paper after folding!

    • How long does it take for the paper fish to descend?

    • How many rotations does the fish make per second? How can we measure this?

    • Change the size of the fish: fatter strip, longer strip etc and see if this has an effect on the above readings

    • Make the half-cuts closer and further away from the ends and see if that has an effect.
