Hi Bloggers,
I made a lava lamp, Hope you enjoy watchng it. It worked a little bit!
I think it is a chemacle change because when the tablet and water combine it creates carbon dioxide which are the bubbles, the bubbles carry the coloured water to the top of the oil and then they pop and the colour sinks back down to the bottom.
Hi Roisin,
ReplyDeleteWhat a fun experiment.I like the background picture.I wish I could have done experiments like that at school.Yes you are right it was a chemical change. Can you add all different colours of food colouring at the same time? Great team work with your sisters and mum assisting you.Keep up the good work.
