- The chocolate bar comes with a secret invisible wrapper which makes the chocolate invisible if you need to hide it, a bit like Harry Potter’s invisibility clock. We decided this might be a bit difficult to engineer at the moment, but maybe instead of making the bar invisible the secret wrapper could make the chocolate look like a pencil case or book.
- Each segment of the chocolate is a different flavour with a special mystery flavour in the last piece.Something like super strong popping candy or extra swirly praline
- The chocolate bar includes 3 thin layers, one white chocolate, one dark chocolate and one milk chocolate.
- The packaging would be noise free, so you can eat it in the cinema without disturbing anyone.
The winner will receive an all-expenses paid trip to the Bournville Factory in Birmingham to engineer their winning design alongside chocolate experts and hear from a real life engineer, plus a trip to Cadbury World, and an iPad Mini.
Ten runners up will win a family ticket to Cadbury World.
