Here's how we made them.
Gospel Sensory Bottles
Red, blue, green, yellow food coloring
Glitter, beads, buttons, & rubber bands in gold/yellow, black/blue, silver, red, white, & green
How to do it:
Empty and clean a plastic bottle.
Add beads in the bottom.
Fill about 1/4-1/3 full of baby oil.
Dye the water desired color. Note that when making black combining food dyes you'll end up with more of a purple shade.
You'll want to make gold, dark, red, white (use clear water), and green.
Add the colored (or clear for white/clean) water filling it up to the base of the neck. Glue the lid on securely.
Now you can use them to talk about the gospel whenever your little one shows an interest.
