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.
To barter means to trade goods directly rather than through the medium of money. Thus a barter economy is one where money does not exist or has ceased to be functional. It means consumers have to gain goods through exchange. Primitive economies developed through bartering goods. But, this is very inconvenient for a developing and more complex economy. Therefore, money tends to involve as a way to facilitate transactions between two people. An example of a barter exchange may involve swapping a bag of nuts for some fruit or meat.
