Play the 2nd one here: http://scratch.mit.edu/projects/17807844/ Click on an ingredient to add it to the cauldron. Keep adding ingredients until you've made a potion. After you've made a potion click the green flag to reset and make another potion. There are 8 potions; try to make them all! Good luck :) If you want you can mention which potion is your favorite in the comments...
