This experiment poses a risk of fire, so perform it outdoors. Pour some water into the glass bottle through funnel. Next add caustic soda into the bottle with spoon. Be careful while adding caustic soda. Make sure that caustic soda does not come in contact with your skin. It may cause itching. After adding caustic soda close the lid tightly because caustic soda is hygroscopic and can absorb moisture from the air. Now take aluminum sheet. Make small size 4 Strips of Aluminum foil. Put these strips into the bottle. Next, put the balloon on the top of the bottle. Don’t shake the solution. It causes a vigorous reaction.
