Why do Astronauts Float? is supported by listeners like you. So wouldn't you like to *own* it? Get it on your Mac or PC today, and for all days going forward!


My biggest goal with TestTubeGames is access

Science museums are great! (I used to work at one.) Science outreach programs are great! (I took part in several.) But not everyone has access to enriching science spaces. They can be hard to get to, far away, or cost prohibitive. I want to give folks a way to explore interesting concepts no matter where they are, and without requiring many resources.

That's the reason so many of my projects are completely free. I want the smallest barrier to entry possible.

That said -- making and giving things away for free is not, on its own, a sustainable business model. If you are able to, please consider supporting TestTubeGames. You can...

  • Pay to download some of my projects, and support their development. (GSim, Shocktopus)
  • Donate to the cause
  • Buy a rad Raptor pin
  • Share these projects with your friends -- so I don't have to spend as much time/money on marketing

Thank you for your help supporting interactive science resources.
