Only use Gatorade or G2 bottles for the sensory bottles they are a heavier plastic so they hold up better and keep a unison look so everything looks good. They come in different sizes you can find smaller ones for small hands if you need to.
Make sure to ALWAYS seal your bottles securely! I cannot emphasize this enough. Unless you want your bottle opened and the contents poured out. SEAL IT… with glue. Duct tape can be peeled off by a determined kiddo. Glue is much harder for them to open up.
Calming Glitter Bottle:
Fill your bottle half way with hot water. How hot? I made it as hot as my tap water would go. Next I emptied my glitter glue bottle into the discovery bottle. Then add some CLEAR glue to fill the bottle. Next SHAKE, SHAKE, SHAKE, and then SHAKE some more. Until it all combines.
Alternate Method: Fill half of the bottle with water and half with corn syrup. Add glitter, beads, paper clips etc. The corn syrup and water mixture makes the glitter fall slowly for dazzling effects.
