Boil Jello and corn syrup in water with some food coloring, then pour the syrupy mixture into Lego molds (trays that shape the liquid into a Lego brick). In this video, the inventor of this makes gummy Lego in 7 different colors, neatly squirting the gooey gumminess into the trays using a ketchup bottle.

Double-Trouble Dominoes
April 6, 2021Thought this was a great video of geometric growth in action by @uoftphysics Prof. Stephen Morris
https://www.youtube.com/watch?v=y97rBdSYbkg Starting with a ~5mm domino you get to a one ~1 m in size in 13 domino topples. Overall, this chain reaction represents a 2 billion-fold amplification!

Dominoes are little toy rectangle tiles with dots on them. People like to stand them up on end in a long row, so when the first domino falls over, it knocks over the next domino, which knocks over the
next…pretty soon you have a rippling wave of falling dominoes. In this simple but amazing video, Stephen Morris shows that a little domino can knock over another one that’s 1 1/2 times as big in each direction. Then that one can tip over one that ‘s 1 1/2 times as big again. In this domino chain, the first one is only 1/4 inch tall, but the 13th domino weighs more than 100 pounds! If he kept going, the 29th domino would be as tall as the Empire State Building (1,454 feet). We’d all better get out of the way!
