Speedy Science...

Sometimes you just need some high speed science tricks to keep your child amused! This one is perfect.

What you need:

  • Piece of printer paper
  • Scissors

1. Take a piece of printer paper and fold it in half lengthways, the open it out flat again. Then fold it the other way and again, open it up and lay it flat.

2. Cut from the longest edge up to the centre along the fold...

3. The next bit is a little tricky, you want to fold the paper into thirds. Take the short side and fold it over until it looks like it is 2/3 of the way across and pull the opposite side so it is folded over 1/3 of the way. Crease the paper then open it out again. 

4. Turn the paper so the cut is at the top and then cut along the third folds to the middle. You should have something like this...

5. This is where the magic happens. you don't need to write the numbers on the paper, in fact it's better if you don't, they are just there to make the explanation easier...

Lift up flap 4 so that it is vertical. Then grab 2 and fold it under so it's upside down and laid flat where 5 used to be and 5 is now upside down where 2 was.

This will give the illusion that there is too much paper for the holes. If your paper is all one colour it's really baffling but if you use paper with a different colour on each side, you can see that the paper is twisted!

  1. That is clever...and SO quick and easy! I love the puzzled look on Ebi-kun's face in the last photo. :-)
