High School Why Haven't Lighter Density Liquids for Swimming Pools Been Invented?
The salty dead sea water was a good example :) -

You're right. Probably would be too hard to stay afloat. -

That's a great post. I understand you now. Ill just look up bouyancy to grasp the term ;) But in generel I get your point. Back to topic though. Why don't you make water that requires 20% of your bodyweight to lift you. It would be able to swim in, and not hurt when you land in it? -

but that makes no sense? You are way easier to lift in water? So you have to at least feel lighter? If you weighed 100 kg it feels like 50 in water if a persons lifts you etc? -

High School Mass vs Weight: Understanding Relative Atomic Mass
So weight is the gravitational pull? And mass is how big something is? -

Right. What if your weight is 40 kg then? 0 and 20 in the other water? -

so that's about 25 kg in normal water? -

High School Why Haven't Lighter Density Liquids for Swimming Pools Been Invented?
Today on my way to a swimming lesson, i wondered why swimmingpools with other kinds of liquid mass in them havn't been invented? I was wondering if water with a different density and lighter mass wouldn't equal that a human beeing would more easily go through the water and not hit himself as bad... -
