Squash, bend, twist, stretch - Online practice 3

Read before answering

An adult's imaginary demonstration uses a strip of thin card. After a gentle action it curved instead of staying straight. Squashing presses flatter; bending makes a curve; twisting turns parts around; stretching pulls longer. Discuss the supplied record. For a real demonstration an adult selects allergy-safe materials; no sharp wire, snapping elastic, force or objects near faces.
