I made this purchase while I was looking for lava lamps. This is incredibly entertaining for all ages. I gave this as a gift to my boyfriend we want to purchase more for our friends.
Thank you for this product. I find it very cool. This is actually a gift for my boyfriend, since he is so evolved into science. I tagged him in a video that I saw and he was really interested in it so I decided to get one for him. Can't wait til Christmas!
LED light and extra magnet for SPIKE ferrofluid display
The magnets are incredibly strong! The light adds a nice effect. My 8 year old carries his ferrofluid jar all over the house, playing with it all day.
