Sweet Volcano

Have you ever seen a fizzy drink volcano? Well I have and I'm going to tell you how it erupts when you put mentos in.

In a fizzy drink there is CO2 (carbon dioxide). That's how bubbles are formed when CO2 gets covered by H2O (water). So when you put mentos in the fizzy it brakes the H2O and the CO2 escapes and multiplies before it flows over the sides.

So now you know what happens when you mentos in a fizzy drink try it for yourself.

Rainbow magic

Rainbow Magic

Have you ever wondered what happens when you put milk, dish washing liquid and food colouring in one bowl? Well I can tell you what happens.

It mixes. But how does it mix by itself? you may ask. In milk there is minerals vitamins and fat. Fat loves to chase dish washing liquid so it mixes the food colouring and you see it bubble and mix like a rainbow. If you use water instead of milk it will not mix because water only has minerals and vitamins. Also half of the dish washing liquid is scared of water. So the food colouring just shoots off to the sides.

Now you know what happens when you have milk, dish washing liquid and food colouring in one bowl try it for yourself and see the magic begin.
