Leaf and gauze became to white. Leaf became to small and veins of the leaf were burnt in the glass.

Almost of paper string and wool were burnt too.

The mirror’s shape remaining in the glass, but it doesn’t look like mirror.

Aluminum foil didn’t burn, and looks shiny.

The cap of pen and plastic decoration were disappear from the glasses…..

Just white vestiges showing those were here.

The clip’s wood parts disappeared from the glasses, metal part remaining.

<Result of the experiment>

– Metal, leaf can put into glass (doesn’t burn)

– Wood, paper, wool, plastics can not put into glass (will burn)
