The middlest thing (15 out of 29) - BALLOON
I folded an origami balloon today at work. Actually I made two. The first was too small and I couldn’t get it to work right. The second was a bit better. I didn’t have square paper, I had to make my own. I took a picture of the second one, but I can’t upload it yet, so I will add it later. This thing was also known as a water bomb when I was younger - I guess it can hold water for 20 or 30 seconds…
