Walking through walls may be in the realm of fiction, but what about passing your whole body through a postcard? Is that any less challenging? Task: take a postcard or small piece of paper and cut out the largest hole you can.
Perhaps you thought to start this way.
And you would end up with this.
Not nearly big enough! Stumped? Continue on for the solution.
Fold the paper in half lengthwise.
Make a cut starting from the folded edge. Stop short of the opposite edge.
Make a second cut the same way at the other end.
Now cut along the folded edge, leaving the end pieces intact.
Make another cut next to the first one, in the same manner as before. Continue making cuts the same distance from each other.
The paper is now cut into strips attached at one side.
Now turn the paper around and cut the second strip down the middle, again stopping before reaching the end.
Repeat with all the strips.
Now look at what has resulted.
Unfold the paper and carefully stretch it outward.
Now you’ll have no trouble passing through! Challenge your friends to do the same. Are they clever enough to figure it out?
