I'd say "Sleep" causes them to try. Same as "Backflip".
The Hypnotist in the video isn't dealing with conscious people, he's dealing with people in a hypnotic state. Which, if you believe in such things, means that their waking minds are unconscious and they're in a suggestible state of quasi-awareness which allows him to manipulate their perceptions. He can "Put them to sleep" 'cause they're already asleep and he's just ending the quasi-awareness state.
"Sleep" wouldn't break concentration. Neither would "Backflip", though impact with the ground might do it.
"Daydream", however, would apply immediate disadvantage to perception checks and end concentration. That one is freaking -clever-. "Meditate" would also end the concentration and apply disadvantage to perception for the same reason.
I also like the idea of telling a spellcaster concentrating on a spell to "Fly". Because it means they'll cast Fly, or Levitate, in an attempt to follow the command, ending their concentration on the previous spell. -Very- clever. But only works if they've got the right spells prepared.
