Make your own… Seaweed Goo!

Have you ever touched seaweed with your foot while strolling on the beach? Did you notice how it often feels slimy? This is because seaweed is covered in a jelly-like layer that prevents it from being damaged by the waves.
As well as being essential to the survival of many marine creatures, as food and as a habitat, seaweed (and phytoplankton) is also responsible for producing about half of the total oxygen on Earth!
We use it as food, as an anti-inflammatory, as a fertilizer and as a soil conditioner. Scientists have also discovered that seaweed can even be used to thicken just about any liquid, and so, seaweed is used as a binding agent in products such as toothpaste and shampoo.
With this experiment you’ll witness this last property of seaweed; you will observe how seaweed acts as a binding/thickening agent in food, by mixing alginate with water.
