Lunchtime project: a primitive cardboard projector



Our son is home sick so we came up with the idea of making a cardboard projector during lunch today. We used an old Jungle Oats cereal box, a toilet roll core and cling wrap for a basic lens.

We secured the cling wrap using an elastic band (hair elastic in our case) and we stuck a small piece of paper in the shape of a tree on the lens.

It is really primitive and we worked out that the LED on an iPhone projects a very clear silhouette through the projector.

Our son is working on a rocket shape to project on his cupboard door which has glow in the dark shapes and he is going to create a sort of shadow movie for his sister.

    Very cool and creative. Think my son will love to do this as well.

      Thanks. We’re working on a variation of the old silent movies too. I showed my son what storyboards look like so he is working on the story he wants to tell and we’ll probably start shooting a little movie this evening when I get home.

      It should be fun. It won’t win any Oscars but he digs this.
