Here's my variation on a sensory water bottle that works well for tiny hands to hold-- use your empty bubble wand tubes!
First rinse out the bubble solution. With the one I used, the wand pulled out of the cap really easily. (You could cut the wand off if yours does not pull out). I then filled the tube with a mixture of corn syrup and water to make it thicker and slow the items down inside. I used pony beads in this picture, but paper clips, pom poms, sequins, glitter, or any small colorful items work well. Be creative! Make sure to glue the cap shut when you're done with super glue, E600 glue, 527 glue, or anything that bonds well with plastic. Enjoy!
