New LEGO flooring is HEAVIER than granite??

We're back at my LEGO Fortnite Gravity Lab to test the weight of a new material, "Generic Plank Floor" (made from regular wood). It appears to be at least 20% HEAVIER than "Castle Thin Floor" (made from granite). ‪@LegoMoxy‬ asked me to do a test with the same material on all 3 elevators to confirm they are uniform. I did those tests as a control group when I first built the lab but I'm repeating them here for everyone. 02:21 Experiment #5 testing the weight of equal stacks of 3 different materials 08:16 Control #1 testing the same stack of "Futuristic Floor" on all 3 elevators 13:52 Control #2 testing the same stack of "Castle Thin Floor" on all 3 elevators Let me know if you have any questions or want to see any specific experiments!
