*random* Share whatever you know how to do that is amazing and awesome at the same time *nodnodnod*
For me...well...
I know how to
turn liquids pink through titration in chemistry :3
But going by my actual occupation in geology, I know how water moves through the ground, how
artesian wells work (by the way, De Drinkplaats would be an artesian well since it's always flowing), what a confining unit is and how it affects groundwater, uhh...how to tell the difference among an igneous, metamorphic, and sedimentary rock...uhh...the biology of some organisms found as fossils...yeah, lots of stuff.
