Science Class Potion

Are you good at science? Then help our girl create a special potion for the science class to save her dead flower. You have a lot of ingredients and you have to combine only four of them. You have bugs, dirt, coffee beans, leaves, poison, dead leafs, rocks, grass and bones. If you get the mix right, your flower will bloom and you will get an A, but if you get it wrong, you will see a lot of unfortunate things. The flower can become alive and carnivorous, which will surely be an F, you can get a gorgeous red rose that gets black after a few seconds, which is definitely worth at least a B, you can get a crazy combination of little yellow flowers and a deadly plant for a C, or you could got something very creepy and will fail the class. Try as many times as you want until you get it right. Have a blast!
