</gallery>When agar medium is ready it's time to put slime mold, oat flakes, and food coloring inside. Around two weeks before the experiment some of the students took slime mold with them to home, and I was one of them. During this time slime mold grew very well, and I'll use it as "mother culture" for my experiment.<gallery> | |||

</gallery>I took some parts from the Mother Culture and placed them in two Petri dishes. For the coloring process I took liquid food coloring (four colors) and judging by their composition, I assume that slime mold should like this—since the dye consists primarily of syrup and sugar. After placing slime mold and oat flakes inside Petri dishes I made a couple of color drops on top of flakes. <gallery> | |||
