I started the water rocket computer model back in the early 1990's - it was the thing that started me off on water rockets.

A version of my original computer model was used in Wilf's Programmer's Workshop on the cover disk of PC Plus in 1997. Since then, I have updated the model a number of times and, to a large extent, it has outgrown the limitations of including extensive help within it - merely providing a guide as to what you should be doing while you are using it.

These help pages are intended to provide a more complete and versatile set of help pages that you can print out if you wish, or have in a separate window running on the desktop. If you have downloaded these files, you should be able to access all of the pages without reference to the Internet, as the Internet site is restricted to the actual construction of water rockets whereas these pages refer specifically to the running of the computer model.

The computer model itself will run either on a DOS machine or on a Windows DOS box. If you are doing the latter, you can select the size of the text in the DOS box by selecting the appropriate options.

I have written these pages using MicroSoft Internet Explorer to check them, using a screen resolution of 1024 x 768. They also work well in 800 x 600 but on lower resolutions, there may be problems with graphics sizes. The graphics are designed for the screen but if you want to print them out, you can reduce the graphics by zooming out (reducing their size by right-clicking and selecting Zoom Out) and they should still print well but use less ink.

These pages do not contain any frames, scripting or active controls - containing only images and HTML so there should not be any problems with any company's security policy unless that policy is based upon ignorance, superstition and paranoia.
