An aspect includes an agent carrier and an agent disposed in an inner cavity of the agent carrier. The agent includes an expandable foaming material and electromechanical signal blocking particles embedded in the expandable foaming material. An aspect further includes a sensor and agent release mechanism configured to release the agent from the agent carrier based at least in part on a determination, via the sensor, that the agent carrier is within a predetermined distance via the sensor from a vehicle.

The present disclosure provides a continuous launcher including a pressing tube having a first hollow portion therein, a launch unit having a second hollow portion therein, disposed at a front side of the pressing tube in a spaced manner, and launching a launch object using air compression force, a piston supply unit provided at a rear side surface of the pressing tube, including a plurality of pistons therein, and supplying the pistons one by one, a piston loading unit connected to a rear end of the pressing tube, and moving the piston to a load position, and an operating fluid supply unit supplying an operating fluid to press forward the piston, wherein the launch unit includes a launch tube having a launch hollow portion with the launch object therein, and a diaphragm.

A competitive game for use with bottle caps for entertainment. The bottle cap game comprises of a bottle cap shooting gun and a wall mounted game board. The wall mountable game board includes a plurality of apertures having differing diameters. Players utilizes the bottle cap shooting gun to remove a bottle cap from a bottle and shoot the cap at the apertures in the game board. A digital counter integrated into the game board displays points each time a bottle cap is shot through one of the apertures on the game board and updates the score. The bottle cap game provides users with an entertaining game for parties involving any type of beverage served in bottles.

An apparatus includes an energy source and an expansion structure. The energy source is configured to convey an amount of energy operable to increase a pressure of a compressible gas disposed in a chamber. The expansion structure is configured to be placed in fluid communication with the chamber and to receive a flow of the compressible gas in response to the increase in pressure. The expansion structure includes an inlet having a first diameter and an outlet having a second diameter greater than the first diameter and is configured to allow the compressible gas to expand as the compressible gas flows from the inlet to the outlet such that a supersonic free jet of the compressible gas exits the outlet. In some instances, the supersonic free jet of the compressible gas can accelerate, relative to the expansion structure, a projectile disposed outside of the expansion structure.

A projectile cartridge that can be removably attached to a flying vehicle is disclosed. A system can include a first flying vehicle, a projectile attachment mechanism configured with the first flying vehicle, a projectile cartridge that contains a projectile, the projectile cartridge being removably attachable to the projectile attachment mechanism, a weight attached to the projectile, the weight being configured in a releasable configuration in the projectile cartridge and a drawstring configured with the projectile. After firing the projectile, when tension is applied to the drawstring as the projectile approaches or envelops a second flying vehicle, the tension can cause the drawstring to close the projectile down to secure the second flying vehicle.

An air-soft gun includes a grip; a high-pressure air canister disposed in the grip; and a remaining compressed air release device including a channel member threadedly secured to an end of the air canister and including an axial channel and a sealing ring; a rotatable cap releasably secured to the channel member; a biasing member fastened between the cap and the channel member; a striker including a needle on a first end, an internal passageway, an inlet proximate the needle and communicating with the passageway, an outlet proximate a second end and communicating with the passageway, internal threads on the passageway proximate the second end, and a threaded fastener driven through the cap into the internal threads to secure the cap to the striker. The inlet is blocked by the sealing ring in an inoperative position.

The fishing lure launching device is a mechanical device. The fishing lure launching device launches a payload. In the first potential embodiment of the disclosure, the payload comprises one or more elements selected from the group consisting of a fishing line, a fishing lure, a leader and a swivel. An example of a fishing lure is a spinnerbait lure. The fishing lure launching device launches the payload on a controlled trajectory. The fishing lure launching device is a pneumatically operated device. The fishing lure launching device comprises a bucket, a transfer shaft, a thrust structure, a trigger valve, an adjustable pressure regulator, and a gas source. The payload is contained in the bucket. The transfer shaft attaches the bucket to the thrust structure. The thrust structure generates the forces necessary to launch the payload out of the bucket. The trigger valve initiates the operation of the thrust structure.
