Optimum stomp rocket size

A4 wide - that is 210mm of photocopy thin card ( 160 GSM )
rolled around the 22mm waste pipe tube ( from local DIY ) snug but loose fit.
Nose cone approx 80mm long ( but try longer ) and filled with 2 crumpled sheets of copier paper ( 80 GSM )
Fin size 50mm high and 50 mm wide.
This rocket reached at least 50 metres using a 2 litre bottle.

Have a great time and perhaps send us a link to your video.

Happy summer to everyone and thankyou for your support... so until September ... have a STEMTASTIC holiday.

Last session - fantastic first year

Okay so this is it. WE have reached the end of a fantastic first year. We want to carry on with the STEM CLUB next year ( into year 8 ) and have many plans.
On this last session we experimented to ascertain the best criteria for a stomp rocket - pure fun with logical testing and evaluation combined,
Results posted soon.

Penultimate stem session of term ( Summer term 2009 )

Sorry to everyone about the meeting needing to be on a Monday evening. We had to do this due to other commitments. Same for the last week - next Monday ( 5th July )

Photos to come soon.

The attendance was low as some students did not remember that we had said it was to be a Monday - nevertheless we had a good session which looked at one variable per rocket. Next session we will test each rocket and log the results before designing the ultimate stomp rocket.
