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.
Isn’t this one of the most beautiful sensory bottles you have every seen! It makes me smile it is just so bright and cheery.
Color Mixing Gel Bottle
I buy my hair gel at the Dollar store in the biggest tubs they carry. I almost always buy clear every now and then I buy blue because I use it a lot. The red and yellow I used in this I made mixing the gel with liquid watercolors. I used red, yellow, and blue hair gel. I then dropped a marble in to help mix the colors a little. The only problem with this bottle is that once the colors are mixed that’s it. So generally I just use two colors at a time. The bottle is awesome no matter what. It is neat to watch the air bubbles and marble move through the gel.
