Baby You're a Firework
Ultra rare0.1%ObjectiveOptionalAnywhere
Launch 10 fireworks in 10 seconds.
Fireworks unlock for 3,750 bytes and print for 1 Explosive Powder each (backpack or Small Printer) - so this is really a Sulfur errand: 10 powder means 20 Carbon and 10 Sulfur, condensed on Calidor or Atrox.
Make your 10, then either line them up on the ground and sprint down the row holding the Use key, or do it properly: slot them all onto storage, wire up a button repeater, and fire the whole battery at once. Behold the monobeast of a light show, and the achievement with it.
