Birthday Cake

For my girlfriend's birthday I jumped out of a birthday cake for her. Before doing so balloons, confetti, a giant candle, a strobe light, guitar and music all came out of the cake first.

Shown here is an undecorated cardboard frame I made for the cake.

Design constraints:

- quick to make

- fits in honda civic trunk

- fast to setup

- not super flimsy = wood stiffeners

Solution:

- use half corrugated cardboard that rolls up and make the larges annulus fold along the center.
