Kitchen Counter Science: Baking Soda and Vinegar Glitter Bombs

My 11 year old daughter, "E" made baking soda and vinegar baggy bombs at school as part of a science unit on liquids, solids, and gasses. It is a classic science project that can be found on numerous science project websites. She came home and wanted to make some with me and her sister. 
We decided as a group it would be more fun to add our own colorful, rainbow twist to the experiment and that is how our baking soda and vinegar glitter bombs were born! 


For this kitchen counter science experiment we gathered our supplies from the kitchen. 
We used: paper towels, baking soda, white vinegar, neon food coloring, small zipper sandwich storage bags, 
and some glitter from the art studio. 

To start, the girls poured out some baking soda (a generous tablespoon) and some glitter
onto a square of paper towel. 
They folded the paper towel into a little packet to keep the dry ingredients separate from the wet ingredients. 
Set the little packet aside. 

Then, they poured a cup of vinegar into a sandwich zip-top bag and added some food coloring
to make it extra colorful. 
Carefully hold the paper towel baking soda packet at the top of your bag while you get help zipping it shut. 
See photo of the vinegar above. 

After the bag is sealed shut, drop the baking soda packet into the vinegar 
and give the bag a quick shake as you toss it away from you and into the grass. 

The baking soda and vinegar will combine and form a fizzy liquid, 
the bag will fill with gas until it bubbles and pops! 
Get ready for squeals of excitement and anticipation as they wait for the explosion.

The end result is a glittery, colorful mess. 
If you used liquid watercolor instead of the food coloring and tossed the baggy bombs onto white poster board, paper, or foam core, I bet you could make some really cool abstract art!
