Experience Weightlessness

Where: Varies (Austin, TX)
Cost: $5197
Date: TBD, Monthly flights touring the country
Link: Zero Gravity
Comments:The second cheapest way to freely float in space. Fly into the upper atmosphere where the plane accelerates at exactly the rate of gravity. The result is everything in the plane (including you) behaves exactly as if you were in space. Wash, rinse, repeat!
