Several years ago, when the ISS repeater was still working, I was doing a
satellite demo for the scouts under the K9BSA callsign, working stations
right and left with 20 - 25 scouts gathered around the rig, when astronaut
Mike Fincke picked up the mic and said "hello to the scouts from the
International Space Station, NA1SS!"
I swear, the collective "thud" of the scouts' jaws hitting the floor could
be heard for miles...

It all depends on the knowledge and skillset of the scouts in question. My
last significant AMSAT demo was done during JOTA, and at that point we had
between 100 and 150 young people come through the shack doors throughout the
weekend. We didn't have a huge amount of time to explain everything or go
really interactive with the control or tracking, and to be honest most of
them were amazed enough that they could hear voices coming back from space,
so when we listened in to one of the Italian ARISS contacts, they were even
more thrilled! My trusty FT-847, SatPC32, ERC-M interface and Kenpro KR5600
did the job nicely, we made quite a few QSOs, and we got to listen to a full
ISS pass - something the 80 odd people who poured into the shack when it
started will likely not forget for a long time yet.
