you have to wait in line to sign-up for a time slot to participate in this exhibit, but it is so worth it. you are able to choose how you want yours to be done and the staff just follows your directions. you pick out three colors and with each color you choose the direction and shape by pushing the bottom as hard or soft as you want. you tell them when to drop the color and when to pick it up as well. and when it's finished you get to bring it home!
it's incredible with the size and amount of exhibits, that everything is well functioning, clean, and accessible.
