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.

I claim: 1. A safe air-pressure-launched toy rocket system, comprising: 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 said reservoir to a high pressure; a valve connected to the reservoir
I claim: 1. A safe air-pressure-launched toy rocket system, comprising: 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 said reservoir to a high pressure; a valve connected to the reservoir and configured, when opened, to release high pressure air stored in said high pressure reservoir to the toy rocket to launch the toy rocket; and two releases configured to be operable by different hands of said user, wherein the releases are connected to the valve in a series-open configuration, whereby said valve is closed only when both of said releases are operated. 2. The safe air-pressure-launched toy rocket system as claimed in claim 1, wherein said mechanical releases are spaced apart by a distance of at least approximately eight inches. 3. The safe air-pressure-launched toy rocket system as claimed in claim 1, wherein said high pressure is at least approximately 5 psig. 4. The safe air-pressure-launched toy rocket system as claimed in claim 1, further comprising a nipple along which the toy rocket slides, wherein the high pressure air is released from the high pressure reservoir to the toy rocket via the nipple. 5. The safe air-pressure-launched toy rocket system as claimed in claim 1, wherein the system is linearly arranged in the following order: the manual air pump; the high pressure reservoir; the valve; and the toy rocket. 6. The safe air-pressure-launched toy rocket system as claimed in claim 1, wherein the system is configured such that, before the toy rocket is launched, a distance between the two releases and an upper tip of the toy rocket exceeds a maximum distance between the hands and head of a person. 7. The safe air-pressure-launched toy rocket system as claimed in claim 1, wherein the system is configured such that, before the toy rocket is launched, a distance between the two releases and an upper tip of the toy rocket is at least approximately two feet. 8. The safe air-pressure-launched toy rocket system as claimed in claim 1, wherein said releases are mechanical. 9. The safe air-pressure-launched toy rocket system as claimed in claim 8, further comprising a floating bar connected between the mechanical releases and configured to close the valve only when both of said mechanical releases apply pressure to said floating bar. 10. The safe air-pressure-launched toy rocket system as claimed in claim 9, wherein the valve comprises a compressible tube, and wherein the floating bar is configured to compress the compressible tube only when both of said mechanical releases apply pressure to said floating bar. 11. The safe air-pressure-launched toy rocket system as claimed in claim 1, wherein said releases are electric. 12. The safe air-pressure-launched toy rocket system as claimed in claim 1, wherein the pump comprises a check valve. 13. The safe air-pressure-launched toy rocket system as claimed in claim 1, further comprising a relief valve connected to the high pressure reservoir. 14. The safe air-pressure-launched toy rocket system as claimed in claim 1, wherein the toy rocket comprises: a water reservoir configured to contain water; and a nozzle connected to the water reservoir, wherein the pump is configured to enable the user to pump air into the water reservoir to a high pressure. 15. The safe air-pressure-launched toy rocket system as claimed in claim 14, further comprising two nipples along which the toy rocket slides, wherein the high pressure air is released from the high pressure reservoir to the toy rocket via the nipples. 16. The safe air-pressure-launched toy rocket system as claimed in claim 14, wherein the system is configured such that, when the water reservoir contains water and the water reservoir and high pressure reservoir have been pressurized with air, and when the valve is opened, the toy rocket is launched by forces provided from both: a) the high pressure air released to the toy rocket; and b) an impulse reaction caused by water being ejected from the nozzle at a high pressure. 17. The safe air-pressure-launched toy rocket system as claimed in claim 1, wherein the pump comprises a linear piston pump comprising a piston portion and a cylinder portion, wherein the piston portion comprises a stirrup, wherein the pump is configured to enable the user to pump air into the reservoir at least by gripping two handles connected to the cylinder portion with the different hands of the user and inserting a foot of the user into the stirrup. 18. The safe air-pressure-launched toy rocket system as claimed in claim 17, wherein the releases are connected to different ones of the two handles. 19. A method of operating a safe air-pressure-launched toy rocket system, comprising: providing the safe air-pressure-launched toy rocket system as claimed in claim 17; gripping the two handles; inserting the foot into the stirrup; operating both of the releases to close the valve; reciprocatingly operating the pump to pump air into the reservoir to the high pressure; and releasing at least one of the releases to launch the toy rocket. 20. A method of entertaining, comprising: providing to a child the safe air-pressure-launched toy rocket system as claimed in claim 1; inciting the child to operate the two releases; inciting the child to pump air into said reservoir to said high pressure by using said manual pump; and inciting the child to release at least one of the two releases to launch the toy rocket.
