Discovery Bottle DIY Tips
Play with the seashell bottle craft for a day or two to make sure you like how fast the seashells move.
If you want the shells to move a little faster, add a bit more water. If you want them to move slower, add a little more clear liquid hand soap to your seashell sensory bottle.
When you are happy with the way your shell calm down, the jar moves; fill it all the way up with water or liquid hand soap, so there is no air in it.
Air, soap, and water make bubbles. If you shake it up with air in it, it will become a frothy mess that may not ever settle.
Even when you fill your sensory bottle all the way up with the seashell sensory bottle recipe, it may be a bit murky until the contents mix and settle.

Why did you use hand soap in this instead of glue?
Good question Hannah! Glue is generally used in glitter bottles to help the glitter suspend and swirl. For other bottles with heavier pieces like this, you can use either clear hand soap, or clear dishwashing soap to make the water more viscous to slow the shells down. Clear hand soap is thicker so you will need to balance it with water, while dishwashing soap will need less water if any. I hope that makes sense.

I’m thinking of doing this activity at a party that is only 3 hours long, so I don’t want this beautiful craft to be murky during the party. Can you mix the water and soap ahead of time for 10 children and then let them pour the mixture into their bottles all at once?
In my mind’s eye, it sounds possible. Just make sure you fill each bottle up to the top before you put the cap on and it just might work. Let me know how it goes!
The superglue … did I miss what its use is? Is it for sealing the lid?
Yes, JJ! The glue is for sealing the lid shut once you are satisfied with your sensory bottle DIY. I’m sorry that I did not make that clear!
