Super interesting and a bit addicting!
Originally saw this in a sensory toy website but it's been sold out forever. Was excited to see it available on Amazon although concerned about shipping because its glass and liquid filled. I was SUPER impressed with the way it was packaged. It arrived quickly, in tact and after trying it out I was pretty amused myself. Its worth the buy if your kids enjoy sensory fidget type things.  Took me some time to actually put it away myself!
