It is virtually impossible to torte (cut in half) a sheet cake of any size without it cracking or crumbling. A technique used by professional bakers is to bake multiple thinner layers and simply stack them between delectable icing layers to create the height you need for the cake design.
Barter is a system of exchange where goods or services are directly exchanged for other goods or services without using a medium of exchange, such as money. It is distinguishable from gift economies in many ways; one of them is that the reciprocal exchange is immediate and not delayed in time.
Bartering has evolved today into a legitimate method of exchange of goods and services. One of the first evidences of bartering is in 6000 BC. The barter system traded all sorts of goods and services, such as weaponry, food, or tea.
