Laser Fun Day Volunteers Needed!

Good afternoon Optical Sciences,

Laser fun day is fast approaching on the first of March, and we need you to help run demos and teach kids about optics. We are looking for people to work one of two sessions. Morning shift will be from 9:00 am to 11:45 am and then the second group will take over till 3:15 pm. As an added bonus we will be feeding all the volunteers as well, so if you’re interested in volunteering please email and let us know what time you would be available.

Below is a list of demos we are planning to use, if you are familiar with any of these demos and have a preference for which demo you would like to present then include that in your email. No experience necessary come help and have a good time, and tell your friends.

Look forward to seeing you there.
