For my experiment I got a cup full of water. I put blue food colouring in too, then I mixed it all up.I put baby oil in to the cup. The baby oil floats on top of the water because it is so much lighter than the water. Did you know that? When I put acid reflux tablets inside the cup full of water, blue food colouring and baby oil it starts to bubble.It starts to bubble because the acid makes it bubble.
What you need:
- water
- food colouring
- baby oil
- acid reflux tablets
