K is for kid-friendly Toys
You can fill a discovery bottle with any kind of kid-friendly toy but you have to look for items that are small enough to fit into the opening of your bottle. Â Often times, you can find small items in the party supply section of a store…
Above is an alphabetical list of store-bought type of kid toys or kid-friendly materials that can usually be found in some type of mini-form and will work well for play and exploration (some items you may want to add water or other type of liquid and for others, you may not)…

L is for light
Discovery bottles are always better to observe on a light table or in a window. I always keep a set of discovery bottles near my light table…
The light table has a way of capturing the children’s attention to new properties of the discovery bottles. The children will often take more time to notice color, movement, bubbles, and other qualities of the discovery bottle when they can view it on the light table.

M is for Magnifier
Be sure to add other tools for play to your discovery bottles that invite additional types of play and exploration. Items like a magnifying glasses (for closed bottles), tweezers (for open bottles), Â scales, clip board and pencils, and anything else you can think of that invites the children to go past the obvious and will bring a new dimension of play with the bottles….
and M is for Magnetic
Another fun way to add a new dimension of play to the discovery bottle is by adding magnets and magnet wands. Â In this discovery bottle are pipe cleaners. The wire in a pipe cleaner is magnetic although you will want to keep the weight of the pipe cleaner very light so the magnetic wand can easily pick it up and move it in the bottle…

N is for Nature
Don’t overlook the many wonderful items from nature that can be added to a discovery bottle. Think of the discovery bottle as a hands-on aquarium or terrarium that young children can hold, shake, and examine….
Again, the items from nature you choose to place in the bottle may go well with or without water. It all depends on the items but since this is all about exploration, I say just go for it and see what happens…
O is for Oil
Oil is often used in liquid discovery bottles because of the way water and oil separate. Here are a few things to consider when adding oil to your discovery bottle…
- Baby oil is clear and I like to use it over other oils like cooking oil. But all oils will separate from the water.
- If you add color, the color will not mix with your oil, it will mix with your water.
- It is better to have more oil than water in your bottle if you are wanting the colored water to wash down through the oil.
- The water will always sink to the bottom of the bottle and the oil will always end up on top of the water.
