Fun inexpensive science project

My daughter had wanted to make a vortex and these worked great. Just the right size for water bottles or soda bottles. Just remember to take the extra plastic tab off the bottle to screw these down completely.
Great product for the money

My 11 year old needed something for a science project for some etc credit! These were easy to use and he even shared some with friends and his cousins! Good deal, 10 was a bit much but we put them to good use!
Great! Just clip the bottle ring

The media could not be loaded. Tried it first with the ring from under the bottle cap and it leaked like crazy. But I snipped those off and poof! Just give it a whirl and the water starts swirling! Great times!
Work fine

These work fine but leak on all size bottles I have tried. Might try ordering bottles suggested on Amazon.
Just have paper towel handy and don't use over anything you don't want wet
