If you want to change the color of your platform, it is easier to do so before you start building. Go ahead and use markers or paint to create a snowy, white setting to build upon.
You can also cut a Styrofoam ball in half and then hot glue it onto your base. This will allow you to then build on top of the Styrofoam, guaranteeing an even, circular-shaped igloo.
You can even build a series of smaller igloos around your main one, creating an igloo village.
While a sugar cube igloo might sound tasty, avoid eating it. The raw egg whites could make you sick.
Be aware that you can also use a hot glue gun to connect the cubes to the platform and to one another. However, you’ll want to be very careful or you could accidentally melt the cubes in the process. If you are building on top of a Styrofoam ball, it is possible to reverse this process and build from the top down.
Salt will bring the freezing point of the down below 32 °F (0 °C). Thus, it partially melts the cubes together. Then, by placing them in the freezer, they will freeze together again as the temperature drops below the new freezing point.
It isn’t necessary to throw the milk caps away. You can use them as decorations either on top of your dome or around it.
If you want your igloo to be edible, stick with marshmallows, icing, and straight pretzel sticks for support.
