Sinkholes, Climate Change, and Magnets - Oh my!

In celebration of Thirsty Thursday (an alliteration that I just made up), I have a sweet video for you of a very thirsty sinkhole in Louisiana:


Terrifying.

Now what would cause something like this? Mining! Specifically a salt mine in this case, but sinkholes have opened up because of oil drilling, fracking, and even the withdrawal of water. Humans need to be careful when extracting resources from the environment because there's often unintended consequences.

Speaking of unintended consequences, Congress just voted almost unanimously to add an amendment to a bill verifying that climate change is real. Somehow there's been denial of climate change despite 97% of scientists agreeing that it's happening and it's man-made - there's consequences to digging carbon out of the earth and setting in on fire. Check out this link if you want more info.

To end on a happy note, here's a slow-mo video of magnets CRUSHING objects:


Sweet.
Even those these are VERY strong magnets, they still only have a limited range - that's why the scientists have to push them closer together before they attract enough to move together on their own (violently).
