Best thing for Astronomer-pockets.

The Black Hole Model really helps to get an understanding of one of the most complex phenomena in our universe - black holes. I use the model during my outreach activities at the observatory Astronomie-Werkstatt "Sterne ohne Grenzen" in the Dark Sky Park Eifel Nationalpark in guided stargazing sessions outdoors under the starry night sky and indoors in my presentation for demonstration purposes. I congratulate STEMCELL for this unique and inspiring idea to hold a black hole model at ones fingertips. Best, Harald Bardenhagen

Very cool! It may be the coolest thing I own. To actually possess a dinosaur fossil of your very own, is an amazing feeling :)

Neat item, fun to have.

This is a great meditation aid. Love it.

I got this as a gift for my little sister who loves birds. After delays in shipments, the team priority shipped it to make sure it would get there in time. My sister loves it!

Alles bestens! Bei Bedarf gerne wieder.
