How to make a lava lamp the easy way by Jorgie A list of easy instructions ,so that all of you can do it at home !! ( with all the scientific bits left in for those science loving maniacs ) We are not making shop bought ones we are making proper homemade lamps I repeat homemade lamps!!

You will need: An empty water bottle Vegetable oil (can be any sort of oil) Clear tap water Food colouring (any colour will be just as effective) Alka seltzer A bright light (torch) Funnel Cereal/cardboard box with a hole cut in it for the torch
