Used Scuba Diving Equipment – You have to have one item only, no more, and this item cannot be a large machine (e.g. scuba diving equipment does not count as one item, it has many parts to it). Please also tell me how you would use the item.
P.S. Depth is 10-20m so snorkels won’t work =S
Using a balloon/bucket to trap air would be hard to hold on to because of the density of air. Therefore, suggestions like these will not work =(
As for the hosepipe idea, do you know how much energy would be required to **** air through that? And also, when you removed your mum from the hosepipe, water to go into it… =S
oops soz ppl, forgot about that, yeah, you’re underwater (20m-ish)
There is a solution to this, and anyone can do it (not just Olympic swimmers or something).
