Pine glue!
My friend Lucian took this picture. Weโve been collecting white pine sap for weeks. Finally, we heated the jar it was collected in, boiling it in water, to melt the sap itself. Then we added crushed charcoal in a 1:1 ratio. Then, we mixed it with a stick and collected blobs of sap on the ends of them. When we want to stick something, we can use this stick, heat it up and use the sap mixture to glue things.
