Say goodbye to boring bathtimes and have a blast with these Finger Tips Bath Bombs! You can buy all the ingredients you need for Bath Bombs from the chemist and supermarket. Sieve two tablespoons of cornflour, two tablespoons of citric acid and 60g of baking powder into a bowl. In another bowl, put three tablespoons of oil - almond or coconut oil works best - a few drops of your favourite essential oil to give it a nice smell and a few drops of food colouring. Mix all these ingredients together. Add the liquid to the sieved ingredients, and give it a quick mix with a spoon. Then put your finger tips in and get mixing - until it turns into a crumbly mixture. To make the bath bomb mould, a ping pong ball cut in half works brilliantly. To cut the ping pong ball in half - rest it in some modelling clay and make a hole in it with a sharp pencil. Use some scissors to cut around the middle. Fill both halves of the ping pong ball with the mixture. Then squeeze the two halves together and neaten it off round the middle. Carefully take off both halves of the ping pong ball and you should have a perfect bath bomb. Keep going until you've used all the mixture - it will make 3 or 4 bath bombs. Why not give it a go and brighten up your bathtime!
