- Strongly compact the mix to have a good consistency.
- Place the mold in the freezer (here is the trick).
- Wait 2 hours (The next step will help you in this difficult task =D ).
Step 7: Play !
While the bath bombs are freezing, you will probably still have a small amount of mixture.
Fresh mix strongly reacts, so it is time for demo effects sessions [see the video =o)]
To enjoy this, put your remaining mix in a small amount of water.
Step 8: What Happens ?
Bicarbonate anions react with protons from acid to produce carbonic acid, which decomposes to form carbon dioxide:
H+ + HCO3- -> H2CO3 -> H2O + CO2
For bath bombs we have :
C6H8O7 + 3 NaHCO3 => C6H5Na3O7 + 3 H2O + 3 CO2
Thus, the bubbles are from the carbon dioxide created by the reaction between baking soda and citric acid.
Chemistry is fun !!!
Step 9: Let Dry and Add Essential Oils
- Place two leaves of towel paper in a box.
- Put the unmolded and frosted bath bombs in the box and let them dry 3 days.
- Once dried, add a drop of each essential oils on each one.
