I’d say throw it up to the appropriate height. You don’t need exactly 10m and it’ll replicate the drop event perfectly.

Note to grapefruit tossers: Please practice safe science. If you're going to throw an object 10 meters straight up in the air and see how it impacts the ground, you need to not be the ground it impacts, or at the very least your science will be ruined, if not your day as well.

If we learned anything from Lawn Darts, it was this.

Those who survived lawn darts learned nothing.
