To make the item “nerd” in Little Alchemy, you need to start by combining the items “book” and “glasses” together. Doing so will create the item “nerd” in the game. After combining the two items, you can discover different items by experimenting, and combining these combinations together. For example, combining nerd with the item “computer” will create the item “nerd programmer”. With the nerd item, you can further experiment with different combinations of different items to discover other combinations of items related to the nerd world. Keep combining a variety of items, and you may eventually be able to combine enough items to create the item “time machine”. Have fun!
