Natural consequence for hitting / throwing

[Biboundeo]

I’m struggling to find a logical natural consequence for when DS1 (almost 3) throws things or hits DS2. When his behaviour is unacceptable outside (e.g. he’ll run on the sidewalk - our rules are clearly written and often reminded), for instance he will loose his autonomy (not decide what he prefers so do between playground and shopping, have to go in the stroller instead of having fun on his scooter, etc.) but he just threw a night light at us from 5ft away and we’re shocked. He got a very stern no, throwing hurts and we stopped what he was doing, we said we needed time to think because we were so shocked but now I don’t know what to.
Any idea please?

Throwing - can't be trusted to be where there are things to throw, so moved somewhere else until ready to be calm/gentle, tidy up any mess caused by throwing, make it better for anyone affected by the throwing.

Hitting - can't be trusted to be near others, moved away until ready to be calm and then need to make amends with whoever was hit, e.g. Cuddle or sometimes I get DD to help with a little job like clearing the table.

Thanks a lot, didn’t think about asking to tidy up after, it’s a good way to « repair » the relationship I think, great you reminded me!
Removing sounds like a good option. This is the one I’ve been testing for the last couple of day: as soon as he’s about to hit/throw, I stop what he’s doing and redirect him.
