have the Dr write on a piece of paper and seal it in an envelope and take it to a bakery. tell them to make a gender reveal cake according to what's inside the envelope. that way you won't know until you have the cake :)

omg ha ha really well then how would a gender reveal be done by who?

Awe you should do one either way! I thought the whole point was to not find out until the gender reveal. So it would be a surprise to you too.
