Hexaflexagon
Recreated from the school website that’s blocked.HEXAFLEXAGON
Today I created a Tri-Hexaflexagon. A Tri-Hexaflexagon Is a Hexagon that Flips inside out repeatedly. I thought it was really cool from watching Vi HHeart’s video, but she goes so fast that It is hard to follow the instructions on how to make one, If there even is instructions. So I decided to figure it out.
First you take a long strip of paper, and fold it into 10 equilateral triangles. Next label them 1-10. Then, count the first 3 and fold the rest up. After that make a hexagon shape and place the end in the back. Finally, Fold the flap over the triangle that it fits with and glue those together. Tada! Hexagons have symmetry so you can fold it into a trapezoid, and that into three triangles, to make it bendy. After doing some more research I found out that there was a hexaflexagon club at Princeton university called the flexagon committee, with four famous scientists in it. Arthur Stone (creator of the hexaflexagon), Bryant Tuckerman, Richard Feyman, and John W.Tukey.Ali’s version

Loaded Dreidel
It’s Chanukah and we play dreidel, a game of luck. There are four sides to a dreidel. Each side has a Hebrew letter. You spin, and if you land on Gimel, you take all the money. If you land on Shin, you add money to the pot. If you land on Hay, you take half of the money in the pot, and on Nun, nothing happens. To start, all the players put a penny in the pot, and each player takes a turn spinning. We have six dreidels, and you can pick your favorite to spin.
I made a video to figure out the probability of it landing on Gimel X times in a row. It landed on Gimel seven times and then on Hay (I was really lucky). I wondered what the probability of landing on one Gimel would be. I made a probability chart for landing on one Gimel. The probability of landing on one Gimel is 1/4; but then what is the probability of landing on 7 Gimels in a row? I figured that since for one Gimel the probability was 1/4, the probibility for two Gimels would be 1/4 times 1/4, and for 7 Gimels it woud be 1/4 x 1/4 x 1/4 x 1/4 x 1/4 x 1/4 x 1/4 or (1/4)7. That equals about 0.00006. I think there is something up with this dreidel! Or I’m just really good at spinning dreidels.
