Hooked on Science - Exploding Baby Bottle (07/22/2019 - 07/28/2019)

INGREDIENTS

• Hard Plastic 8oz Baby Bottle

• Rubber Nibble Without Hole

• Alka-Seltzer

INSTRUCTIONS

STEP 1: Fill the hard plastic 8oz baby bottle, half of the way with water. Describe and classify the water by its observable properties.

STEP 2: Add two Alka-Seltzer tablets to the baby bottle and securely attach the collar and rubber nipple, without holes, to the top of the bottle, shake the bottle, and observe. Describe and classify the contents of the bottle by its observable properties.

STEP 3: Carefully and slowly unscrew the collar from the bottle. What happens? Did adding the Alka-Seltzer to the water result in a new substance?

EXPLANATION

When the Alka-Seltzer is added to the water, in the baby bottle, a chemical reaction happens, which creates carbon dioxide gas. The carbon dioxide gas fills the rubber nipple, without a hole, causing the nipple to expand. When the nipple is carefully and slowly removed, some of the gas quickly escapes, forcing the nipple off the bottle and into the air.

SCIENCE SAFETY

PLEASE follow these safety precautions when doing any science experiment.

• ALWAYS have an adult present.

• ALWAYS wear the correct safety gear while doing any experiment.

• NEVER eat or drink anything while doing any experiment.

• REMEMBER experiments may require marbles, small balls, balloons, and other small parts. Those objects could become a CHOKING HAZARD. Adults are to perform those experiments using these objects. Any child can choke or suffocate on uninflated or broken balloons. Keep uninflated or broken balloons away from children.
