cool before and after i made. i cultured bacteria by leaving grass submerged in water overnight, it produced dense colonies of bacillus. i think it's hay bacillus. i injected a bacteriostatic antibiotic beneath the coverslip, it led to a dramatic reduction in motility. my friend got really mad at me for doing this he thought i would make a superbug or smth lol. i filmed this with a nikon plan apo 20x and a cmos camera.
