For younger kiddos, like infants and toddlers-
Wash and dry any size plastic bottle, such as a Gatorade bottle or Coke bottle. For the little kids, I like the smaller sizes, like 12-20 oz. Be sure the bottles are thoroughly dry inside before starting (although some of these will have water in them).
Main idea- place items inside the bottles and glue lid shut. Some ideas that are big hits:
little jingle bells
colorful art feathers
fun foam collage shapes
uncooked beans or rice
Placing some or all of these items in a dry bottle will create a shaker in most cases. These are typically fairly light weight and babies love the noise! To create a 'wet' version, place certain items inside the bottle. Then fill the rest of the way with water. while twisting on the cap, give a slight squeeze to get rid of any air bubbles.
things that work well in the wet bottles:
1/2 colored water 1/2 baby oil
food coloring or paint
My favorite sensory bottle for little kiddos involves a very small amount of white Karo syrup and those tiny black plastic ants from halloween decorations. Put just enough Karo syrup in the bottle to coat the inside walls. add as many plastic ants as you'd like. glue the lid on. When this bottle is turned, the ants will slide down the wall, giving the appearance of crawling! This one is SO COOL!
For Older Kids:
Again, be sure the bottle is drier than dry for this one...and a larger bottle, such as a 2 liter, will work best. Find random objects that will fit in the opening of the bottle. One i made today had a blue lego, a red rubber dinosaur eraser, a penny, etc. Be sure to use at least 5 or 6 items for a small bottle and 8 or 10 for a 2 liter. Stick the items in the bottle and write down what you put in there. then fill the bottle with uncooked rice or dry sand, leaving an inch or so of empty space for movement. Laminate the list of objects and punch a hole in the corner. Tie the object list to the neck of the bottle. Now you have an "I Spy" bottle for older kids to enjoy! Have them turn the bottle and search for the items on the list! Great for long car rides!
