Abstract: An improved drinking can enables a user to have fluid return into the can after drinking The improved drinking can comprises a can body comprising a contoured bottom edge immediately adjacent to a bottom recess. The can body further comprising a can top mechanically coupled to a spout. Where the spout is shaped to funnel fluid back into the can body. The bottom recess is shaped to enable a first improved drinking can to sit upon a second improved drinking can where bottom recess covers can top. This protects the drinking area from becoming contaminated during shipment, storage, and display. The can body is covered with a mural where the mural is covered by a mural cover comprising a tab such that the mural cover can be removed by applying force to the tab displaying the mural.

Abstract: An engine propulsion system is configured to utilize bursts of pressurized media in order to transmit mechanical energy. The engine propulsion system includes at least one cannon, wherein each cannon is configured to displace the pressurized media and further includes a firing pin casing configured to accommodate a firing pin. The firing pin is configured to transmit the mechanical energy when moved thus allowing the media to exit the cannon.
