Pond in a Bottle

Make a sensory bottle to go along with the book, Ribbit!

Mesmerizing and oh-so-simple, this easy sensory bottle is sure to be a hit! This is the first sensory bottle we are introducing, so we’re keeping it simple, but we’re looking forward to showing you all the cool things you can add to these bottles in the future! We made this bottle to accompany our reading of  Ribbit!. The book is about a little pig sitting on a rock in a pond, trying to make friends with the frogs through a chorus of “Ribbit’s”. So we made our very own pond in a bottle to pass around while we read. We also used this as our science experiment. Oil and water vary in density, making this little sensory bottle possible. We suggest making the bottle(s) as a class and making predictions and using the time to discuss density, why the oil and water do not mix, and why the floats to the top! Add the food coloring AFTER adding the water and oil for an extra cool demonstration of the differing density and how it affects the movement of the food coloring.


  • Bottle (we used a Fiji Bottle and removed the label after soaking it in water for about 20 minutes)
  • Funnel
  • Water
  • Oil (we used vegetable oil)
  • Blue food coloring
  • Hot glue gun & glue


  1. After removing the label from the bottle, fill it just over halfway with water.

2. Add oil and fill to the top

3. Add 3 drops of blue food coloring (watch closely!) the drops will sit on the line between the water and oil for a little bit before diffusing into the water. Pretty neat!

4. Apply hot glue to the inside of the lid and then quickly fasten to the bottle
