To make a sensory water bag, simply fill up a ziploc with little items and water. You can use a lid, beads, pieces of straws, a toy lizard, foam letter stickers, and pom poms or anything else you can think of. Then, tape off all sides to make sure it doesn't leak. Here we used packaging tape duct tape is good too. If you have a food sealer, use that.
