Pumpkin soft water snake novelty toy smile face for 2014
These are slippery little suckers, and we love them! The challenge: hold on to them, and stay holding on to them! More often than not they will wiggle through your fingers, leaving you empty-handed but smiling. Filled with glittery-blue liquid and some squishy-fish, these water snakes are a fun way to learn about friction, or more to the point 'anti-friction'.
What you get
Slippery Water Wiggler 13cm long
How does it work
The soft, water-filled plastic casing has little friction and easily slips through your hands. The special tunnel-like design facilitates the slipping movement, making them hard to hang-on to and lots of fun. Slippery Water Wigglers are an engaging, hands-on way to experience and demonstrate friction, or lack there-of. Discuss: when is friction a good thing( sneakers, car brakes), and when do we want to minimize friction in real life(slides, ice skating). Ask, What is the by-product of friction? Rub your hands together and experience friction – do they feel warm after a while?
• Force and movement
• Friction as a force that slows motion, pulling in the opposite direction to movement. Friction essentially transforms kinetic (or movement) energy into thermal ( or heat ) energy.
