ok I need help! My DD has decided on a cake for her sweet 16 this Thursday. She wants a round bottom , topsy turvy for the next layer, then a round ball cake for the next layer THEN another topsy turvy for the top layer. How the heck do I get them all to stack without squishing the ball cake? I have it planned for a slab of wood covered with foil for the base... then a wooden dowel to support the whole thing BUT how to not squish it ?? HELP PLEASE!!! Save my sanity until atleast the party!

each cake needs supports within the cake...maybe you should go for something more simpler if you don't know much about supports

Make the ball out of rice krispie treats and then cover in fondant.

With the short time, other than changing the plans, what about using styrofoam balls (covered in fondant), instead of actual cake for the balls? You'd still have to support them, so they don't squish into the cakes they are above...so not sure if that will help too much.
