Surveyors in ancient Egypt had a simple tool for making near-perfect right triangles: a loop of rope divided by knots into twelve equal sections. When they stretched the rope to make a triangle whose sides were in the ratio 3:4:5, they knew the largest angle was a right angle.
Can you fit the five pieces at bottom into the two smaller squares above the right triangle? Then can you fit the same five pieces into the larger square below the right triangle? If you can do both, what have you done?

Brain Game: Brain Bender
Looks easy, right? Uh-uh. Give this one a try. It’s much more difficult than it looks and it’s really fun!
Brain Bender helps improve cognitive control and reaction time. Click the button that corresponds to the color of the word, not the word itself. This really throws your brain for a loop!
Wow, this Circuitry puzzle game is challenging. The idea is to fix the broken connections in the circuit to complete the circuit and turn on the light bulbs. This is a great game for training your concentration and ability to visualize spatial relationships.
Blingy little shells from Ruzzetti & Gow (via Turquoise Chic) run anywhere from $100 to $1700 bucks (!!!) but we’re betting that a can of silver spray paint could give you the same effect for far less (tip: you can also try “hammered silver” spray paint for a less-shiny-but-still-metallic finish).
One of the two spirals in the illustration consists of a single piece of rope that has its ends joined. The other spiral consists of two separate pieces of rope, each with joined ends. Can you identify which is which using only your eyes?
Janet’s Note: It took me a while to get the hang of this game, but it’s really fun once you figure out what you’re supposed to do. [Hint: It was not intuitive to click "Next Level" to begin the game.] The idea is take the colored ball that appears at the bottom and target a matching color at the head of the line of balls in the maze, shoot the ball from the bottom to that spot and try to get three in a row of a color to pop them out of the line, and to do so before the first one in line reaches the end of the maze.
