Consumables (per student):

• 3 tbsp Baking Soda
• 2 tbsp Epsom Salts
• 1 tbsp Citric Acid
• 2 tbsp Cornstarch
• 2 tsp Baby Oil  
• 2-3  Drops of soap colorant  
• 1 tsp Water  
• Spoon
• Gloves
• Ziplock Bags
• Black garbage bags for tables
• Growing sea creatures
• Dixie Cups/Plastic Cups  
• 2 drop essential oil (optional)

‍

• Put all the dry ingredients in the paper bowl: baking soda, cornstarch, and Epsom salts. Use a spoon to blend the dry ingredients, you want a fairly smooth consistency throughout the entire mix.  
• Put all the liquid ingredients in the Dixie cup: water, baby oil, soap colorant  of your choice, and the essential oil of your choice. Mix the liquids with a popsicle stick. Don't worry about separation too much, you are not going to get a full emulsion.  
• While mixing with your hands, slowly add small amounts of the liquid to your dry ingredients. If the mixture starts to foam, you are adding the liquid too fast. Quickly mix the reacting ingredients into the non reactive part and you should be able to stop the reaction.
• When all of the wet ingredients have been added, you should have a mixture with the consistency of slightly damp sand. It should clump together when you squish it and not fall apart. If not, mix up some more water/oil solution and add until proper consistency.
• *It’s important to note that the bath bombs should not be too liquidy, otherwise they will not set and continue to expand.  
• Place mixture in mold. Place a grow-in-water animal capsule in the mixture.

• Pat the mixture in the mold tightly.
• To fasten the drying process, place the bath bombs in their molds in a fridge for 1 day.
• Once dry, gently tap on the plastic, remove the first half. Do the same thing for both sides
• Place in a ziploc bag, and label it with the student’s name.
