These are sturdy and students like them. They truly can be calming to watch.

My kids love watching these, they have thrown them a handful of times and they’ve held up without issue

Wish it took longer for the colors to travel. Still does the job and keeps their attention. Just wish it took longer. We keep these in kids rooms for attitude breaks or take on trips when they are bored.

Got these to pull out of my "bag of tricks" for my 14 mo. grand daughter for the plane. I have these in my classroom for preschoolers and they love these. Sometimes I have watched them play with these for long stretches of time. Its mesmerizing, relaxing & probably a great reset for them. Mine came in great condition & seemed like great quality. Says non-toxic. Still I would check persistently to be sure there are no leaks from maybe dropping. I had fun opening the box and making sure they worked . hee hee Gonna need another set for home . To be on the safe side I will put in Ziploc for the plane. I'm sure its not more than 3 oz. just not sure if the cabin pressure will affect it ? Not too concerned

It was what I was looking for & was both affordable & fun.

Only had a couple days but already my children love them. I bought them for my autistic son to help him,calm down when he's getting a sensiry overload and it works well for that he sat there for hours just watching it. My daughter also enjoyed playing with them even though she doaent have a sensory disorder. The flow is fast but the kids dont seem to mind. It is thin and plastic and if they were to get thrown on a hard surface id assume it would break easily. But so far no leaks.

I bought these because I needed a fun timer that would take “approximately” one minute. Anything with ten seconds would’ve been fine. Both of the timers I received take nearly 2.5 minutes to complete, and it’s not really possible to visually estimate when one minute is up. Thank goodness for free returns.

Stunning color & action! I bought these on a whim and they are way better than the typical toy. In fact, each one is a beautiful work of art and engineering! Great colors certainly, but better yet are the clever designs. Plastic is strong and perfect refractive index match for what must be clear silicone oil inside. That means the colors dance and move apparently like magic, diverging and bending around unseen barriers in their path, when in fact it's just clever science! Fantastic!
