### Is it possible to engineer a liquid with a high density (20g/cm3) ?

Hi, absolute newbie here.

I'm wondering if it's possible to create a liquid substance at regular room temperature and pressure, that would have a significantly higher density than water.

Ideally about 20 grams per cubic centimeter, or higher. (20 times more dense than water)

But any increase in density would help. Even 5-10 grams per cubic centimeter would be great!

I tried searching this through Google and couldn't find a relevant answer.

The resulting substance should not be toxic, like mercury. It should be perfectly safe for humans (and plants and animals for that matter, but at least for humans)

If it is possible, can you provide any information or guidance (even generic directions) as to how it would be done, and from what "parts"/atoms it would need to be done.

Thank you.

Any salt solution is higher as water

But can it get as dense as 5 grams per cubic centimeter at minimum, or denser?

No, on this planet not possible, for what purpose you need this strange thing.

20g/cm^3 = 20 kg/l
