You may or may not have heard of this sequence, where you choose a number, and if it's odd, then you multiply by three and add one, and if it's even you divide by two. Eventually, you will get down to "4,2,1", and it will repeat "4,2,1" over and over again. There is not a known number that does not end with this loop. So, why not make a graph of the number you choose? Also note that this graph will only work with positive numbers, so no negatives or zero. You can either watch the computer graph it automatically, or you can go into manually stepping, where the graph will only continue if the "step" button is held down. I added sound effects that are pitched based on the height of the point the number is on, so you can hear how random it sounds. If you don't like the sound, which you probably won't, you can just mute the tab. When the graph reaches the end of the screen it will continue on a new one. The graph will end once it reaches 1. However, Scratch does a number limit, so if you enter a gigantic number it will say "Infinity".
To be honest, this is really just for fun, but when you graph it out it looks really cool. It's called a hailstone sequence because it is like the hail in a cloud going up and down randomly, but eventually still falls down. Pretty cool! Experiment with different numbers and you will find that some last only a few seconds before reaching 1, and others can go really far before falling down. Decimals are really weird, since they aren't even or odd, but since they aren't divisible by two, they are technically odd. So, when you enter a decimal, it will continuously increase, but for some unknown reason, it will eventually turn into a whole number....
