I saw this neat idea this summer on Learn With Play at Home and just had to give it a go. It’s a water bottle fountain and this experiment using just an empty water bottle, balloon, straw and some sticky-tac (or clay) teaches that air takes up space.
This experiment is so clearly explained step-by-step on Learn With Play at Home and has tips for making it easier or extending it for your child.
My kiddos loved every step of this experiment. I followed the steps almost to the letter and my boys were so curious! I love it when they try to figure out why something is happening, and any experiment with air truly gets them thinking because it’s an invisible force that does something so neat!
(I took several pics, but thought I should just send you to the blog to check it out.)
