Answer 1

Hey mate,

★ How to fill glass half without measurements ?
- First fill the glass about 70-80 % of its volume by approximation.
- Now spill excess water by tilting the glass until edge of water touches rim of upper surface of bottom end.
- Confirm this by checking surface water touches upper surface if bottom and lower surface of top end.

Hope this helps...
