Every year at Whitsun me and a couple of friends leave Leipzig for a weekend out in the nature. Like last year, we've chosen my family's house in Obergeißendorf as this year's destination. Packed with a proper Hi-Fi setup consisting of Robert's turntables, a ton of vinyl, loudspeakers, my amp and heaps of cables accompanied by other DJing gadgets some of us arrived on Thursday. The rest of our 14 people strong party came the day after. It's been six days of relaxing, music, lot's of air-dried sausages, barbecue and draught – mostly outside in the chill winds of Thuringia.

The most fun part was the "rockets" we built based on a rocket game set for kids Christiane gave Marci and me last Christmas. It contained a book with instructions for making rockets in order to fulfill three missions. The First Mission was pretty lame (conceivably not for kids), i.e. you had to put two pieces of cardboard together and weight the rocket's nose with a bit of modelling clay. Then fire off the whole thing with a slingshot-like device.
Marci and Robert, both filled with the engineer's spirit, didn't stop there and tried to accomplish Mission Two. You need some more stuff, here's a quick list:
We took the following steps to build and start the rocket:
I wish I had one of those alluring Tablet PCs to illustrate the building process better. You may have a look at various web sites that describe the issue and the physics behind it.
We had so much fun starting the rocket over and over again. Unbelievable! :-)
I've uploaded two videos of our rocket Marci took with his mobile phone. Video 1, Video 2
