Hooked On Science – Frankenstein’s Hand

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.

INGREDIENTS
• Baking Soda
• Vinegar
• Rubber Glove
• Canning Jar

INSTRUCTIONS
STEP 1: Add 3 tablespoons of vinegar to the canning jar. Describe and classify the vinegar by its observable properties.
STEP 2: Add 2 tablespoons of baking soda to the rubber glove. Describe and classify the baking soda by its observable properties.
STEP 3: Carefully stretch the open end of the rubber glove around the neck of the canning jar.
STEP 4: Dump the baking soda, inside the rubber glove, into the canning jar, and observe. Did mixing the two substances result in a new substance?

EXPLANATION
When the baking soda is mixed with the vinegar, a chemical reaction happens, which creates carbon dioxide gas. The carbon dioxide gas fills the rubber glove, causing the rubber glove to expand.
