- Valentine’s Day Candy Filled Heart Topped Tube
- 2 Effervescent Tablets
- Warm Water
STEP 1: Empty the candy from the Valentine’s Day candy-filled heart topped tube.
STEP 2: Fill the tube ½ of the way with warm water. Describe the water by its observable properties.
STEP 3: Break two effervescent tablets into four equal pieces. Describe the effervescent tablets by their observable properties.
STEP 4: Drop the effervescent tablets into the tube, with the water, quickly push the top onto the tube, rapidly shake, and observe. What happens? Did mixing the effervescent tablets with warm water result in a new substance?
When the effervescent tablets are mixed with warm water, a chemical reaction happens, which creates carbon dioxide gas. The carbon dioxide gas fills the tube and eventually launches the heart top into the air.
