When I'm in free fall, I'm weightlessness for only about 1-2 seconds. Is there any way I can feel weightlessness for a longer period of time?
There are private space companies that will allow you to take a trip to space(it costs around $250,000). Take a trip and go in orbit around the earth or go to another space station. Another solution would be to go to the Zero-G place as Lasse said or fall farther as Rob Jeffries said which are both much less expensive.
