Abstract
A safe air-pressure-launched toy rocket system includes an air-pressure-launched toy rocket, a high pressure reservoir, a manual air pump connected to the reservoir and configured to enable a user to pump air into the reservoir to a high pressure, a valve connected to the reservoir and configured, when opened, to release high pressure air stored in the high pressure reservoir to the toy rocket to launch the toy rocket, and two releases configured to be operable by different hands of the user. The releases are connected to the valve in a series-open configuration, where the valve is closed only when both of the releases are operated.
