Are you looking for an (energizing) activity to get the focus of your audience back after a longer (lunch) break? This is a nice short activity that you can do with your audience to get back to the focus of the group. It is easy to organize and explain and you can fit it into a theme about “different perspectives”.
Ask the audience to stand up. Explain that time is something that we can objectively measure. “We are going to see how good you can estimate how long one minute takes. For this you need to put away your watches, phones and everything else that can be used to measure / read time. Also don’t put your watch or phone in a position that somebody else can see it. Don’t use your fingers to count or count out loud. Remain silent. When you think it is exactly one minute after I say start, you go sit down. You’re minute stops exactly at the moment one you sit down. I will measure who get’s closest to the real one minute. However get’s closed to one minute wins. Is that clear? So I count down to 3, 2, 1, start and on start I start measuring the one minute. When you sit down, you think the one minute is over. Ready? 3, 2, 1, Start!”
Now you need to start measuring the time and also keep trach the time for the first one and the last one who sits down and obviously the person who sits down at exactly one minute or closest to the one minute. As part of the debrief you start with saying the range and then congratulate the winner (round of applause). It is not uncommon that the first person sits down after 40 seconds and the last one after 1,5 minutes. You can use this as part of your story that even about something that is easily measurable, people have different perspectives.
