Did you know?
The secret to moving the slider is lots of friction—a force that resists motion. When you pull a string, the slider twists. This forces one of the straws to turn and lock onto the string. The friction between the turned straw and its string keeps it from sliding. By first pulling one string and then pulling the other, you can make the slider move forward.

The Claw. This game is similar to Stick With Me, but instead of magnets, the slider uses hooks (i.e., claws) that hang down to pick up objects. You’ll need about ten big paper clips. Bend four of them open, poke them through the cardboard, and tape them in place. To play, move and dip the slider to hook the targets—paper clips bent so they have a loop sticking up. The claws grab the target paper clips by hooking them.
