Mars on water

We have been learning about water  on  Mars and filters hope you like it.

Biltong

for the last few weeks we have been makeing biltong's, we had one peace of meat we rubbed salt all on it then we hung it up and waited for a couple weeks then it started to get hard and dry.

When I tasted the biltong it was hard to bite and it tasted like salt.
While I grabbed the biltong it was crumbly.
