The Physics practical gone horribly wrong:
Graciously completed by his Sister-in-Law-to-be (otherwise, THE ONE, and THE ONLY, self-glorifying goddess, who is, The Real Deal
Task: To Investigate a BALLOON CONDOM
Title of investigation: Flying Condoms
Aim of investigation: To determine the effect of the circumference of the opening of a condom on the speed at which it flies in a straight line when filled with air and then released.
Variable to be investigated: Circumference of the opening of a condom
Apparatus:
Lots of string
Metre rule (or if you’re using a super condom, you might want to have many metre rules.)
Kitchen roll (remove all the paper first)
Vernier Caliper
Digital stopwatch (or if you really must, analog could work.)
4 bikini clad girls (to be labeled Amy, Bella, CoCo and Donna)
G.D.C. (unless you can calculate the speed mentally; and if you can, you’re a freak.)
Condoms of variable opening circumference (0.5cm, 1.0cm, 1.5cm, 2.0cm, 2.5cm, 3.0cm; to be labeled C1, C2, C3, C4, C5, C6 respectively.) * Please change the measurements; unfortunately, I don’t really know how big they can get. Yes, SHAME. * [actually, I do know how big condoms can get. A girl did this, if you must know]
Gum (Spearmint works best.)
Procedure:
Blow up the condom C1 – not explode/implode it, but rather, blow air into it. If you really need details for this, it involves taking a deep breath, *drum roll*, putting your mouth to the opening of the condom, and pushing the air out of your mouth into the condom.
Blow air into the condom until the diameter of the airy condom is exactly 3.0cm. Use a Vernier Caliper for this. Be careful not to puncture the condom though.
Using the gum, secure C1 to the kitchen roll. Be sure not to let any of your aromatic breath escape the condom.
Using the string, string up (duh.) the kitchen roll which should have a condom attached to it, and if not, go back to step 3.
Amy should be holding one end of the string, and Bella, the other. They should be standing at least 5m apart – we must not underestimate the avionic powers/prowess of condoms.
When both you and CoCo are ready, release the condom and let it fly like a free bird (WHOO!!~~) along the line of string from Amy’s end to Bella’s end. CoCo should use the stopwatch to measure the time from when the condom is released to when it stops, limp and no longer erect.
Donna should then use the metre rule(s) to measure the distance the condom has flown.
Repeat steps 1 to 7 for C2 to C6.
Record your findings in the table below, using your G.C. to calculate the speed.
Repeat the entire experiment another two times to get an average set of results. (Plus you get to frolic with Amy, Bella, CoCo and Donna longer.)
So there you go. Credits to Naomi "I'm-2-hot-2-handle-goddess-of-hotness" Goh for that insightful look into how a physics practical should be. *hint hint, looks at the T.C.*
