Nasa Spin-off Tech

NASA tech

with the talk of the last shuttle flight and the increasing worries of the national debt people often wonder if NASA is worth American tax payer dollars when currently it only consumes .05-1% of the federal budget.

Here are several "practical" applications that have arisen due to NASA. But really if you are trying to decide if NASA is worth American tax dollars just have a drink of Tang, I mean come on the stuff is delicious!

EDIT: tang was actually not invented by NASA and was only used after the astronauts found the water on the spacecrafts distasteful and used tang to make it more palatable
