Instructions (Part III): Carefully open your Alka-Seltzer tablets, fill a cup with water, and set out your film canisters. In preparation for explosion, create an open/safe space that can be easily cleaned up. Follow your procedure carefully, collecting data throughout. Record data in your workbook. Wear safety glasses. 

Instructions (Part IV): Review the results from each test.  Based on your data, use your remaining tablets and clean film canister to create the ultimate explosion by mixing the perfect combination.  Record a video of your reaction and share it below.
