Water Rocket, Classic Science Toy!

This plastic model rocket (with a mean '50's Sci-Fi/Retro look) can fly up to 100 feet using only water and air pressure as "rocket fuel". Set comes complete with 8" rocket, air pump and fuel feeder. Adult supervision is recommended. -- Where's the Science? -- A water rocket employs a compressed gas to accelerate water through its nozzle as a means of propulsion. The water inside the motor is essentially stationary and is accelerated to the velocity at the nozzle expressed by Bernoulli's equation: P = ½ pV2(the two is squared).
Customer Review: Use your imagination and impress your kids: Don't buy this.
Get some 2 litre plastic coke bottles and some corks at craft store. Use a bicycle pump with a needle (for balls). Experiment filling the bottle with different amount of water and let your kids take turns holding the bottle: It takes off and somebody holding or pumping always gets wet! It will shoot anywhere from 40-80+ feet in the air. Excellent experiment and it teaches kids you can INVENT rather than buy (lazy) fun toys. You will have hours of fun and be the kids hero. We did this in the front yard and met new neighbors (and kids) with the attention we drew. Good luck. Chaz.
Customer Review: Good for little kids but....
If you want to play/learn from some amazing water rocketry and have a ton of fun at the same time this toy probably isn't the best choice. Its good for young kids. If you want a more sophisticated water bottle launcher then check out the one on ebay under "soda bottle rocket launcher". There is also a link to youtube showing a little of what this launcher can do. This launcher holds bottles at 120 psi and sends them screaming into the air when you pull the release cord. The launcher comes in a kit and all you have to supply is the materials for designing rockets. Some common tools are needed for assembly. I purchased this thing and it is quite impressive...and affordable too!!! I highly recommend this one if you want high flying rockets and durability!


In the world of franchising often be franchise outlet or franchisee will wish to sell their rights under the franchise agreement to another party. Since this is a common occurrence amongst franchisees it makes sense to have a clearly defined franchise agreement, which addresses potential or problematic transfers. A franchisor may wish to have a clause in the franchise agreement, which actually prohibits certain types of franchise transfers. And there might be a number of reasons for this. Below is a clause that I put into our franchise agreements all prohibited transfers;

5.2.6 Prohibited Transfers

For purposes of this Section 5.2, without limiting the generality of the foregoing, Franchisors withholding of consent will be considered reasonable if the proposed sale, assignment, transfer or conveyance is to an individual, company, or business entity that Franchisor deems in Franchisors sole opinion to be a competitor of Franchisors or a competitor of any affiliate of Franchisors or a competitor of any sister or co-brand company of Franchisors or a competitor of a vendor of Franchisors, another franchisor, another sub-franchisor, master franchise of another system or a Franchisee of another system which has an affiliate company that is a competitor of Franchisors. Any purported assignment without the prior written consent of Franchisor will be null and void and will constitute a material default under this Agreement.

--- ---- --- ----

A franchise or would be well advised to have a similar clause in their franchise agreement. And I recommend that they consult with an experienced and knowledgeable franchisee an attorney who is a specialist. And explain to that franchise attorney their entire business model so that indeed they can come up with the best clause in the franchise agreement to address this issue. I hope you will consider this in 2006.
