FINGER TRAPS
National Standard: B2
“...objects can be changed by pushing or pulling. The size of the change is related to the strength of the push or pull.” 1
Suggested Use
Have students slide their index fingers into the ends of the Finger Trap. Now have them try to pull their fingers out. Observe how the Finger Trap changes size and constricts to trap the fingers. (To remove, push both fingers push IN and have someone hold the trap in this position. Fingers will now come out easily.)
