What kid doesn’t love something fizzy and bubbly and purely fun! That’s why we love baking soda experiments all year-long. For Valentine’s Day we have already tried fizzy hearts and Valentine baking soda fun. Just a couple of common household ingredients for awesome, fizzing heart soda bombs!

HOW TO MAKE BAKING SODA BOMBS FOR VALENTINE’S DAY

Heart Bombs Baking Soda Science Activity

VALENTINE’S DAY SCIENCE

We came up with a very fun and fizzy theme this month, a Valentine’s Day baking soda and vinegar activity! You can grab the basic supplies right out of the kitchen cabinet and create awesome Valentine’s Day science activities the kids love!

These Valentine’s heart soda bombs are just that! Simple, fun, and engaging for young kids and great for early childhood development. Who doesn’t like fizzing and eruptings? Enjoy simple chemistry for Valentine’s Day!

Heart Baking Soda Bombs

Supplies:

  • Baking Soda
  • Water
  • Dish Soap
  • Vinegar 
  • Acrylic Hearts {craft or dollar store items}
  • Containers

Set Up:

STEP 1. To make heart bombs combine your baking soda with water.

You want to add a small amount of water at a time until you have a sort of dough that you can smooth together and will hold. It should not be soupy. Pack the mixture around your acrylic hearts.

STEP 2. Make as many as you want and pop the heart bombs the fridge or freezer for a little while to harden. You can use “as is” too!

STEP 3. For your container add a bit of warm water {1/3}  and a few drops of dish detergent and then fill with vinegar {2/3}.

Although the baking soda and vinegar reaction is plenty fun on its own, adding a some dish soap keeps the bubbling action going longer. Plus you can end up with a mountain of bubbles.

STEP 4. We colored our vinegar red with a few drops of food coloring to tie in with our Valentine’s Day theme. Also add your acrylic hearts to the container of vinegar if using.

STEP 5. Drop your heart bombs into the vinegar and see what happens.

Optional: Turn it into a little fine motor fun by adding tongs. The tongs are also quite handy for fishing out the hearts!

We also enjoyed dropping our heart bombs onto the tray and using an eye dropper to squirt vinegar directly on them! Make sure to see our Frozen Fizzing Snowmen which are similar and so cool!

HOW DO BAKING SODA BOMBS WORK

These heart bombs are all about a chemical reaction including states of matter! States of matter include solids, liquids, and gases. A chemical reaction is when two or more things mix to form a new substance.

When the acid (vinegar) and the base (baking soda) mix together, they form a gas called carbon dioxide which is all the fizzing bubbling action you see! All three states of matter are present: liquid (vinegar), solid (baking soda), and gas (carbon dioxide).

These baking soda bombs are quick and easy to set up for kids with any holiday or seasonal theme. Plus, they use basic kitchen ingredients and include lots of experimental play time.
