Yesterday (Saturday 25 June 2016) was at the Aviodrome Theme Park Museum the annual Modelling Day in cooperation with IPMS The Netherlands and some model flying clubs.
Unlucky for the visitors the day ended in rain but I am sure everybody present had a nice time.
One of the items was rocket building for kids and launching them. They were water/compressed air propelled and could cover a distance of some 40 metres!
Of course it was a nice occasion to open the 2nd-hand bookshop!
