Marking fluid is a pigmented concoction used in the shop to make marks on metal parts. First the fluid is applied, dried, then scribed. Modern fluid is made from denatured alcohol, shellac (a resin), and gentian violet. My thoughts for sustainable marking fluid are to mix ethanol, flaxseed oil, and Prussian blue. Prussian blue is a pigment which may help the oil dry faster, and it is non-toxic (can be consumed to remove heavy metals). I imagine ethanol may also help the oil dry faster, but I am not a chemist.

If I already have the prerequisite amount of weeks for one event. Can I arrive the first day of the event? Also, does this trade extend to the RMH Jamboree?

I think a rocket furnace for recycling glass and tin cans would be a great idea. Another idea would be a rocket distiller for water purification or alcohol dehydration. The evaporation and condensation in the distillation process could even produce mechanical work like in a steam engine. I imagine an engine similar to a Stirling engine with a hot and cold cylinder, the hot cylinder would be connected to the boiler containing grey water or wine and the cold cylinder would connect to the condenser containing distilled water or spirits. However, I am not sure what functionality an engine would serve at Wheaton Labs. (Edit: Maybe the engine could power blowers on the furnace and a fan to cool the condenser.)

Also, can we trade boot time to attend this event? Since leaving the bootcamp, and for the sake of building such a machine, I have started learning how to weld and use machine tools. I can't wait to be back at the Lab.
