Messy Play: 10 Tips to Keep Messy Activities Clean
Need: 1 Liter bottle, water, cooking oil, food coloring, and Alka Seltzer. Pour 3 quarters of a cup of water into the bottle, then fill the bottle the rest of the way up with your cooking oil. Next you wait until the water has settled at the bottom of the bottle. Use about 8 drops of food color (let the drops get to the division between the oil and water). Drop 1-2 Alka Seltzer tablets into the bottle= fun! 30 mins- hour later just cap it and keep it, it works over and over again!!
