More expo

The expo was good for Hazel to do some shopping. I liked the machines more, my dad would have loved it.

The simplest thing was a fire free cooker; basically a basket lined with duvet. You bring your pot to the boil and then put it in there and it keeps cooking.
The handmade ovens were also impressive.

Another instrument was a stone-crusher, not sure why. You give a wheel with fly-wheel a push and keep going while you put a stone in and crumbs come out the bottom.
To most useful thing was a brickmaker. In this machine you put your dirt and with a huge lever you compress it to a brick.

This brick is kind of Lego shaped, this means you can build a whole building without using mortar. A second one does the same, only it makes slightly round stones, specially useful for making watertanks.
