Scientific Test Tube Valentines

Put a little science in Valentine's Day

Submit A Review

Tired of sending the same old boring paper Valentines to school? Add a little science in with the paper hearts and give a creative, unique Valentine this year... one the kids can learn from after the party is over. This activity is easier and faster than the time it would take to tape a lollipop on a paper Valentine!

Materials
  • Baby Soda Bottles (Large Test Tubes)
  • True Color Mixing Tablets
  • Red and pink M&Ms, Conversation Hearts, red hots, Skittles, confetti or any other candy that will fit in the test tubes
  • Ribbon
  • Small plastic bag

Experiment

  1. Get enough Baby Soda Bottles for everyone on your Valentine list. Fill them with candy or fun confetti. Put on the cap.
  2. Print instructions for a small activity to do with the Baby Soda Bottle after the candy is gone. For some ideas, read our experiment on What is a Baby Soda Bottle
  3. For our Valentines we chose the Make Your Own Lava Lamp experiment and included a small bag with a few Color Mixing Tablets and directions. If you use this experiment, make sure the mixing tablets are marked with a "do not eat" label!
  4. Punch a hole in the instruction sheet.
  5. Tie a ribbon through the hole in the instructions and to the top of the Baby Soda Bottle.
  6. You can cover the caps with fabric or tissue paper for a more festive look since the Baby Soda Bottles come in various colors.
