Introduction

Insert ring magnets in a stiff straw such that every pair of magnets is repelling both the pairs on either side of it. Place a frog at the top and enjoy seeing it jump as you push the upper magnets downwards.

    • Be careful while using scissors/cutters, or any sharp object.

  1. Draw a frog on a sheet of paper and colour it. Cut the picture out using scissors. Cut the picture out using scissors.

  4. Take a 5 cm x 5 cm piece of foam and mark its centre. Make a hole at the marked point using scissors. The hole size should be big enough so that the straw fits snugly into it.

  6. Stack two ring magnets together, i.e. such they are attracting each other. Insert more such pairs around the straw such that all the pairs of magnets repel each other. Insert more such pairs around the straw such that all the pairs of magnets repel each other.

  7. Insert the frog sketch around the stand. Push it downwards such that the magnets are also pressed down. Now release it to see the frog bounce back.

    • Here, the magnets are stacked up in pairs. Have fun playing around with the jumping frog!

  8. Instead of magnet pairs, make magnet triplets and stack them (as done previously with the pairs), each triplet repelling those on either side of it. Insert the sketch and observe if there's a difference in the jump height of the frog. Insert the sketch and observe if there's a difference in the jump height of the frog.

    • Straw coming out - Hole in the foam is bigger than the straw. Make sure the straw fits tightly in the hole.

    • No jumping of the frog - Make sure the repelling poles of the magnets are facing each other.

  9. Place the model in a horizontal position. Instead of a frog's sketch add a sketch of a butterfly and watch it fly.
