Back to School Projects Gallery Back to Holidays Gallery 3-D Skull The Hot Wire Foam Factory is the perfect accessory for classroom projects, holiday decorations, and even for making realistic props for movies. This skull was made by simply cutting out a rectangular block of foam with the approximate dimensions of the skull. The frontal shape was traced onto the block and then cut on the Hot Scroll Saw. Without removing the partially carved skull, the silhouette was drawn onto the side of the block of foam and cut out. Now, when the skull is removed from the foam block it has all the basic shapes and only needs to be rounded out and have the details like the teeth cut out. It helps to make the lower jaw separate, and attach later with wires or pins. That way the jaw can open and close too. For added realism you can carve out the inside of the skull with the Sculpting Tool. Hot Tip: Use Hot Wire Foam Factory Foam Coat for more realism and strength..
