Minecraft Fill size Limit

Reference: https://www.youtube.com/watch?v=uAb_RldOor8

  • Code: this replaces the 145 x 145 from y5 to y100, ~ means relative
    /fill ~ ~ ~ ~145 ~ ~145 command_block{Command:"/fill ~ 5 ~ ~ 100 ~ grass replace",auto:1b} replace
  • Idea is replace with command block then each commandblock do its column which is well within the limit of 32768 blocks
  • Doing too much will be slow, but the job will be done
  • To leave other blocks, the outside replace can be  replace x (eg: replace water / replace air)
    /fill ~ ~ ~ ~145 ~ ~145 command_block{Command:"/fill ~ 5 ~ ~ 100 ~ grass replace",auto:1b} replace water
  • Replacing with grass block will end up getting destroyed, do not know if it is a bug or feature.

Liquid-Phase Exfoliation

Seems the two ways to produce graphene that can be done in kitchens are tape and Liquid-Phase Exfoliation.

  • Tape method is very slow, probably can not produce enough to be useful
  • Liquid-Phase Exfoliation can be done in kitchen, but will need a lot of equipment and safety measures
    • Source
      • Exfoliated graphite 
    • Solvent
      • 40% alcholol in water
      • nmp
      • 90% ethyl acetate 10% methanol (sabesto cleaner)
