Pi
Glass Table Spinner 17.75"

How many digits of Pi do you know? I've got around 75. Great party trick, but it really got me laughed at by the cool kids when I was younger. Now I sell a table spinner with the first 10 decimal places, so who's laughing now? Anyway, if you ever need to solve for the area of this turntable in inches, it's the numbers counted clockwise on it multiplied by 8.875 squared. 

Our beautiful 17.75" Table Spinner is manufactured using tempered glass and a high-quality precision bearing for smooth, silent rotation. Pass food around the table in style! Each turntable is printed with our signature high quality standards and is perfect as a wedding, business, or holiday gift.

1/8" thick. Hand wash with a mild soap and cool water. Not dishwasher safe.
