A shape changing apparatus 10 includes a body portion 12 and first and second appendages 14 pivotally attached to respective first and second opposing sides 16, 20 of the body portion 12 so as to be rotatable about respective first and second axes of rotation 18, 22. The first and second appendages 14 are moveable between an open position and a closed position. Each appendage 14 has a generally arcuate shape. The shape changing apparatus 10 further includes a biasing mechanism 50 coupled to the first and second appendages 14. The biasing mechanism 50 is configured to bias the first and second appendages 14 to the open position. The shape changing apparatus 10 further includes a release mechanism 66 operatively coupled to one of the first or second appendages 14. Upon activating the release mechanism 66 the biasing mechanism 50 pivots the first and second appendages 14 to the open position. |
