Ok well first off... I coulden't find a appropriate topic for this... So general is good as it gets for this... Anyways..

1.Go into tpt

2.Place a decent amount of Uranium.

3.Heat it up all the way up too 9999(While the simulation is paused)

4.Press 2 on your keyboard and watch..

This didnt happen before D: Or atleast last time i checked which was like 3 days ago...

If you dont understand what i mean... Notice the random negative and positive pressure?

I understand why it happens... But its just interesting.. So i thought i would share it :3
