To make an explosion you need baking soda and two lemons. Roll them then put them in the microwave for ten seconds, take them out and cut them in half. Put them in the juicer over a cup. In another cup put a spoonful of baking soda. Add dishwashing liquid and mix it together. Next put in the lemon juice then some bubbles will start to appear. The acid from the lemons reacted with the alkaline from the baking soda.
What acids are in your home?
