How to Store and Freeze Bubble Foam Sensory Play
Best Used Fresh: For optimal results, it's best to prepare the eruption mixture just before the activity, as the reaction is most vibrant and fun when freshly made.
Room Temperature: If you need to hold off for a little while, the mixture can sit at room temperature for up to 30 minutes before you begin, but it may lose some fizz.
Fridge: If you must store leftover mixture, keep it in an airtight container in the fridge and use it within 24 hours for the best sensory experience.
No Freezing: Do not freeze the mixture, as freezing can affect the texture and disrupt the bubbling reaction, making it less exciting for sensory play!

Bubble Foam Sensory Play Delight: Mini Volcano in a Jar Recipe FAQs
What kind of baby shampoo is best to use?
Absolutely, I recommend using a tear-free baby shampoo to ensure comfort for little eyes during the activity. Look for a gentle formula without harsh chemicals, as it will create a lovely, bubbly foam effect without irritation.
How should I store the leftover eruption mixture?
To keep any leftover mixture fresh, store it in an airtight container in the fridge. It's best to use it within 24 hours to maintain its frothiness and excitement. Remember, the mixture is most fun when freshly made, so try to prepare it right before the activity!
Can I freeze the eruption mixture for later use?
No, I wouldn't recommend freezing the mixture. Freezing can lead to a drastic change in texture, which can affect the bubbling reaction. It's best enjoyed fresh. If you really want to prepare ahead, try to stick to refrigerating it instead!

Very common! If you notice the foam deflating, don't worry; you can simply re-whisk the mixture to revive its fluffiness. This can happen if the mixture sits for too long, so keep a whisk handy just in case.
