Science & Industry Discovery Day
Sandford Mill - Sep-2002


This was celebrated at the Science and Industry Museum, Sandford Mill, Chelmsford on Sunday, 29th September, 2002.

It was a hot and dry day when the Sandford Mill opened its doors to the adventurious public to celebrate Science & Discovery Day.

The Club Call Sign, GX0MWT (Marconi Wireless Telegraph) was in constant use logging many dozens of stations world wide. Many Club Members operated the Stations and also acted as hosts to explain to some of the 485 Visitors the role of Amateur Radio.

The Club QSLs via the RSGB Bureau or Direct to the QSL Manager Carl, G3PEM, QTHR.

Our thanks to all who made the day the success that it was.
We were also fortunate that the weather was as good as it was.

An exhibit which was popular with the younger visitors was a demonstation of water powered rockets by CARS Member Dr. Geoff Bowles, Keeper of the Science and Industry Museum along with Education Officer, Caroline Hammer.


The idea is to partly fill an empty plastic cola bottle with water and then pump it up with air. When turned up and pointed into the air and released - it rockets upwards.

This picture shows it at the point just after take-off. It travels some 100s of metres. Perhaps this could be the way to launch the next OSCAR satellite!

It is not recommended to "try this at home".



The famous Marconi Hut which was used for the first public music broadcast in 1922 is used by CARS as their transmitter station for HF.
