Question

Have you tried walking on water yet...?

Answer 1

I've seen those on the river last Summer. Young ones having a blast. Looks like fun to me!!!

Comments

They do look like fun, but I read there have been cases of kids suffocating inside the bubble, so the time inside needs to be closely watched.

Aha yes, that was my very first thought...concern of suffocation...not for my children, unless I myself was right there armed with big pin along with huge scissors.

Answer 2

That looks fun...

Answer 3

Well Tink, I had never even heard of these...and I will tell you, first thought is for their air...after the first few lungsfull, how do they breathe???

Anyway, I learned they are now doing this in South Carolina, and it is the little kid who seems to be the most skillful of all!

As for walking on the water myself, well since 1979 I have always left that to Peter Sellers, one of my very most absolute favourite movies of all time, BEING THERE! (Shirley MacLaine wonderful in this, also.)

Well, at about 1.5 meters in diameter, there are about 1767 liters of air in the bubble. Subtract about 67 liters for the volume of the walker's body leaves about 1700 liters of breathable air. At 20 breaths per minute at about 1 liter per breath means one could conceivably last about 85 minutes, but since workplace exposure limits are regulated at 0.5% CO2 maximum, and since you exhale about 4% CO2 with each breath, a safe time in the bubble would be about 1/8 of 85 minutes, or about 10 minutes.

...and ty for that, Tink, now we know!
