i would like to try sky diving. Have you ever done it?
1_Wizard
I sure have!, Ive been skydiving my entire life, I always bring a strong parachute with me!, Would you be interested in learning more about Parachuting? 
0_Apprentice
Yes I would! Please tell me more. Do you need to do a course or something?
1_Wizard
Well not really its more or less just learning free-falling which is a period during the parachute has not been deployed and the your body gradually accelerates to terminal velocity which can be up to 200MPH!

Okay cool. Do you have to practice in an air tunnel first or something?
1_Wizard
You can if you want but there was a guy names Garnerin that  tested his skydiving contraption by leaping from a hydrogen balloon, So that method is better than being in a small wind tunnel.
