“How thick could you get?” -Ron Weasley when he saw Crabbe and Goyle grab and eat two obviously strange, suspiciously floating cupcakes that were in front of their faces. Hermione placed a sleeping draught in the cupcakes to knock out the Slytherin boys so Harry and Ron could steal their clothes and a few hairs to make Polyjuice potion in Harry Potter and the Chamber of Secrets.
I made these using two realistic foam cupcakes.
