A fantastic set of Tunnels, Spirals, and Flextube tiles for GraviTrax! 

With GraviTrax, building fun has free rein. The GraviTrax ball track system can be expanded infinitely through extensions, which guarantees unlimited building and playing fun. By freely designing the ball tracks and exploring the rolling and flight behavior of the balls, the understanding of science is sharpened and gravity can be experienced up close. 

The STEM mark on our products signals a game category where science is experienced through play. STEM (Science, Technology, Engineering, Mathematics) corresponds to the German MINT (mathematics, computer science, natural sciences, technology). 

Use the free app on Android and IOS for the GraviTrax ball track system with its free editor to build your very own fantastic tracks, and then roll the balls as you watch from different angles. Try endless new combinations and come up with new ideas to build your tracks. Experience the tracks interactively and follow the balls from a variety of camera angles – including in Virtual Reality if you have the right glasses and a compatible phone.

Too loose
Color: Black (Retro Rose), Size: Small
I really like this shirt, but unfortunately it is way too loose for a size S. It looks like a XL. A shirt like that should be tight.

Slick White Shirt
The shirt is actually pretty nice. The material is a bit thicker without being heavy so it isn't see through. The material is also soft and silky on the skin. I ordered a large as I am somewhat between a medium and a large depending on the clothing. The large was a bit big on me. It didn't really have any shape to it. I am 5'10" about 170 and the shirt was too big. If you normally wear a large I would say stick with the large but if you are between sizes size down. I did wash and dry it to try to get some of the wrinkles out and drying it got a decent amount of the wrinkles out. The problem is, and why I took off 1 star is that I assume drying it caused the material to kind of bunch a little around the buttons. The shirt just isn't smooth/flat anymore around the buttons. Otherwise it's a nice shirt I'd recommend for things like resort wear or a summer business casual party.
