Discover Science World Resources: Get Animated with Illusion-Themed Activities

Animation involves the blending of art, science and technology. The process of animation involves illustrating, storyboarding and filming—among other processes. But did you know that animating static images involves the optical illusion of motion?

The basis behind all animation is the idea of persistance of vision, which is how our brains perceive moving static images as images in motion. Scientists attribute this feature to how the visual cortex of our brain processes the visual information we receive (colour, depth, form, etc.) via our retinas.

Research and historical evidence show that we begin to perceive motion and lose awareness of the spaces between the static images when they are shown at a rate as low as 10 frames per second. Cool, huh?

Discover optical illusions for yourself!

  • Learn how images are formed from the combination of information received by rods and cones on the retina in this fun puzzle/relay game
  • Investigate how the structure and placement of our eyes creates depth perception in this random dot stereogram demonstration
  • Explore how we appear to see colours from a spinning black and white disk
  • Investigate how our brains blend separate images by making a thaumatrope
  • Turn a series of static images into motion by making a stroboscope

Discover Science World Resources: Winter-Themed Activities

At Science World, we do our best to up-cycle materials when we are creating science demos:

Use recycled wrapping paper to— Make Paper, Tumblewings, and Helicopters

Make snowflakes out of recycled drink can holders— Snowflakes

Play a holiday tune— Musical Bottles

More hands-on fun:

Create stunning snowflakes— Crystal Snowflakes

Warm up and explore melting and solidification— Candles

Make beautiful, festive trees— Crystal Trees and Gardens

Explore properties of super-absorption— Fake Snow

Use changes of state to create chilly architecture— Ice Cube Towers (and before you make ice cubes check out our blog post Can I Freeze Ice Cubes Faster?)

Trick your eyes with a snowman thaumatrope— Dress a Snowperson Thaumatrope

Bubble Recipes

Ever wonder why Science World’s bubbles are thicker, bouncier and more amazing than the rest? It isn’t a secret; it’s science! Check out our very own bubble recipes.

Our latest recipe calls for Polyetheylene oxide, a cool polymer that helps the bubbles to self-repair. It is non-toxic and used in some food and pharmacy products as a binding/thickening agent. In higher concentrations it also makes pretty cool slime for science fiction and horror movies.

  • 400 ml Dawn dishwashing liquid (blue) 
  • 4800 ml water (warm) 
  • 1g high molecular weight (approximately 4,000,000) polyethylene oxide. 1 g is roughtly 1/2 teaspoon. 

Polyethylene oxide is tricky to find but may be available to order through a chemistry supply company (e.g. Northwest). 

All-Purpose Bubble Solution

This solution is great for most bubble tricks, activities, and experiments. Mix the ingredients gently and let the solution stand for a couple of hours.


  • 1 part water to 1 part Johnson’s Baby Shampoo
  • glycerine*

Bouncy Bubble Solution

You can bounce these bubbles off your clothes! Dissolve the gelatin in the hot water. Add the shampoo and glycerine. Stir gently. This solution will gel as it cools. Reheat it carefully in the microwave (about two minutes).


  • 1 package unflavoured gelatin (e.g. Knox brand)
  • 250 ml (1 cup) hot water (just boiled)
  • 50–70 ml glycerine*
  • 250 ml Johnson’s Baby Shampoo

Thick Bubble Solution

This goopy solution makes bubbles strong enough to withstand a puff of air. When you make a bubble with this solution, try puffing at it to make a bubble inside a bubble.


  • 2.5 to 3 parts Johnson’s baby shampoo to 1 part water
  • glycerine

What does the glycerine do?

Glycerine helps soap bubbles hold water, so that they last longer. It’s very helpful if you’re doing bubble tricks, but less important if you’re mixing up a bucket of bubble solution for preschoolers to mess about with. Most pharmacies carry glycerine. You’ll only need a small bottle—try 1–3 teaspoons for about a litre of bubble solution.
