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.


I have been wanting to make a Layered Density Discovery Bottle ever since I first saw one from Steve Spangler. I am so glad I finally made one. I actually had everything I needed right at home and you may too.
We did not measure we simply poured each liquid on top of the next.
Here is the order in which we poured.

First pour in…
1. Honey
2. Corn Syrup
3. Dawn Dish Soap
4. Colored (or not) Water
5. Vegetable Oil
6. We poured in rubbing alcohol it combined with the vegetable oil and even though it has been several days it has not separated.
7. Lamp oil

Next time I make this bottle I am going to leave out the rubbing alcohol.
