Science Toys Make toys at home with common household materials, often in only a few minutes, that demonstrate fascinating scientific principles. http://www.scitoys.com/ we did this one last week.. http://sci-toys.com/scitoys/scitoys/radio/radio.html#crystal PI for you Pi10k will convert the first 10,000 digits of pi into a musical piece. First of all you have to “select ten notes, and your corresponding selection translates into an integer. The first note you select will equal “1?, the second will equal “2?, and so on. As your computer cycles through the digits of pi, the corresponding notes will play.” Not sure you’ll want to hear the tune twice but i like music & mathematics and think it’s a neat project so thought I should share! http://www.avoision.com/experiments/pi10k/pi10k.html Dedicated to Juice and the Gang.
