Query ~ Can you make a hole in an index card that’s large enough to fit a body through?
Yes.
GB did not believe me, SOOOOooo, I made a wee wager…. One extra big hug for me if I can prove it. He’s at that stage where hugs and kisses are very hard to come by…. too girly, if you know what I mean. If I can’t prove it, then I will play any board game he chooses. Win, win, right?
It’s called topology, and this experiment has been around for a long time. Back in the late 1800’s people would sit around talking and doing parlor tricks, which were often science experiments. They used to do this experiment with playing cards.
Here’s how I did it.
Exhibit A ~ Ordinary index card and boring old scissors

Fold the index card in half

Cut the first slice about an 1/8 of an inch from the edge starting at the fold. Then make all your next cuts about a 1/4 inch apart. Don’t go all the way to the unfolded side. As you can see, I got a teensy bit close on that fourth cut.

Now flip it around and cut in between your previous cuts, going about a 1/4 from the fold.

Here is the IMPORTANT part…. On the folded edge, skip the first section, and last section, of the zig-zag, and cut off a really tiny amount of the fold. Can you see how I skipped that first section?

This is what it should look like before you unfold it.

Now, oh, so carefully, unfold.

It should look like this.

Now make the untrusting child put his body through the ‘hole.’

All the way down…. come on….. you can do it, you skeptical little boy…

For further proof, I offer up dh’s body…. just for the experiment, of course. 

GB…. keep this in mind….. Mom is ALWAYS right. You owe me an extra big hug! Ha!
