now make a hole in the balloon first and then start blowing till it attains a considerable size. secure the balloon at the mouth. u can detect the air inside escaping from the hole but at a much slower rate than in the first case.
now the BIG question WHY IS IT SO ???? |
My guess on the different outcomes between CAse1 and CASE 2 is that:
In CASE 1, the air inside the balloon has no other choice but to burst out due to the quick contraction of the balloon.
In CASE 2, while the size of the hole remains the same, the rate of out going air is affected by 2 factors: the rate of incoming air by your mouth and the contracted volume inside the balloon.
In case the size of the balloon keep equilibrium, the amount of incoming and outgoing air should be the same. That means, it seems to be under control.
To minimize personal perceptions concerning the seriousness of CASE 1, I suggest to mount the balloon under the water tap instead of the mouth.
Then, this test/experiment will have more measurable results.
How far and how quick the water goes out through the hole is more observable/recordable than just with the air from mouth.
It is true that any good idea (like that of ARPAN), will not be presented in full implementations in its first appearance.
