Self-powered pressurized granular particle ejector tool with remote operation

An apparatus comprising:

• a pressurized air source;
• a hopper assembly comprising:
• a containment area configured to store an abrasive material in a lower portion of the containment area;
• an air conduit configured to receive pressurized air from a pressurized air source;
• a one-way valve in fluid communication with the air conduit and configured to provide the pressurized air into an upper portion of the containment area;
• and
• a mixing device comprising a conduit, the conduit extending into the containment area and comprising a first opening into the lower portion of the containment area that is configured to intake abrasive material and a second opening into the upper portion of the containment area that is configured to intake the pressurized air, wherein the mixing device is configured to mix the abrasive material and the pressurized air to create a pressurized stream of abrasive material;
• and
• a delivery conduit comprising a flexible tube having a first end connected to the mixing device and configured to receive the pressurized stream of abrasive material and a second end received by a stylus comprising an exhaust nozzle and configured to permit a controllable ejection of the pressurized stream of abrasive material.
