Making the cupcake tier stand
you'll need:
styrofoam/foam core
pvc pipes
duct tape/ large clear tape
cardboard paper
cupcake papers
rullers
pen knife
Draw a rectangular shape, that fits about 6 cupcakes (or more)
using a compass, make a circle on the ends of each side of the rectangle, starting from the midpoint. you will then have an oval shape

first, spread the number of paper cups you would want to fit in the bottom tier,
keep in mind the shape of the ark is top heavy, so this is only the smallest part of the tier.

once you draw out the oval according your desired size, make sure there's room for the columns to support the tiers.
draw out another 2 level by increasing the base size by 1-2inches each.
(The one below is an increase of 1" per level)

after you cut all 3 levels. stack them together.
push each column until there's a hole on each but the bottom layer (the biggest oval)

starting from the bottom up, use a duct tape/clear tape to hold the pvc pipes together

until finally all 3 levels are done.

cut a cutboard paper around the circumference of the oval. secure with duct tape.
then cut out about 5"x6" of the center for the ramp.
TaH Dahh!...
IMPORTANT NOTE! : make sure to clean all pieces of foam that might have stick. use a damped cloth to wipe all surface of the cake stand.
