We will do not test on animals or/and plants. What we will do is environment studies:
(1) we measure how clean the atmosphere is by vacuuming and filtering air particles.
The result won't be known until we take the sample back to Japan and analyze it.
(2) we also measure pH of snow to examine degree of acidity.
Here is how it is done: store snow in a container and wait until it melts and liquidizes,
then put it into a test tube containing color fixing agent,
and it will show 14 different colors depending on the acidity.
So far I found the snow here has low acidity.
