Various kits were made up. Each kit included a large picture of the model
As each builder arrived, they were given a sheet that explained that their grandfather when he was their age may have build the same model that they would be building today. They put their name and age on the sheet and were helped to select a model that fit thier age and the time they had to build.

I had my Golf Ball Machine and Dave's Wave operating and a Hand Crank Airplane Ride for them to try.

Most of the parents got involved

We had 15 builders who made 16 models. I had 20 kits made up. Everyone seemed to have a good time. Note that there was no shortage of girls
