Experiment - Pine Needles -Temperature Resistance

I made an experiment with Pine Needles, to find out how resistant they are to different "extreme" temperatures!

EXPERIMENT 1: I placed one pair Pine Needle in the OVEN for 2 h , in 60° C
No major change, except for the Needles being slightly spread apart.

EXPERIMENT 2: Pine Needle placed in the FREEZER for 2 h , in -18° C
No change

CONCLUSION: Pine Needles seem very resistant to different temeperatures, especially compared to so called "green" leaves, that probably would have dried or ruptured immediately.
