摘要：An erasable slate system includes a translucent layer adjacent a coloredbottom layer, wherein application of a force to the translucent layer causes temporaryadhesion of the translucent layer to the colored bottom layer in an area wherein theforce is applied. The erasable slate system further includes an extending channel in fluid

connection with the translucent layer and the colored bottom layer. The extendingchannel extends around at least 25% of the length of a perimeter of the bottom coloredlayer. The erasable slate system further includes an air pump in fluid connection with theextending channel via which pressurized air can be introduced into the extending channelto cause the translucent layer to be separated from adhesion to the colored bottomlayer, thereby erasing markings, and via which air can exit the extending channel of theerasable slate system.
