Kelpie Wilson guided an activity to explore charcoal properties by handing each student a small paper cup of biochar and adding a drop of water to it. The hissing sound that results is the sound of water bonding with biochar surfaces and expelling air. This works best with biochar that is very light and porous, like activated carbon. Oregon Biochar Solutions provided the biochar for the activity. A big thanks to OBS and Grant Scheve!
|Firefighters demonstrate why you should not plant flammable shrubs like arbor vitae next to a house. UBET demonstrated how you can turn unwanted shrubs and other material into biochar using simple kilns.|
