Hi Guys,

At the New York Hall of Science we have a Rocket Park where our 
Explainers perform a Rocket Science demonstration. There are no 
electrical outlets out there and so for the past year Explainers have 
done the demonstration without a microphone. Any advice on a wireless 
portable system, something that we can attach to a rolling cart and 
recharge after the demo is over?

Thanks,

Jennifer Correa
