For a quick party idea, or unique recycle decor, take bubble liquid (cheap at the Dollar Tree) and Glow Sticks (available there too!). Pour the soap into a bottle, then crack the sticks to activate them. Carefully cut off the top of a stick and pour it into the bottle. Cap, shake and watch the glow. These don’t last for long but afterwards you can use a blacklight to keep em glowing or refill them if you are hosting a party.
Thanks to Emi and Jana for inspiring me to recreate their bottles!
