I think if you read that carefully that you'll find it's relating to the limit of what an individual container can hold within a wooden storage box!

The previous page on the met website covers the areas the the police licence and the starting quantity is listed as 0.1Kilos (100g)

The Police licensing of Storage can be divided into the following three categories:-

? Licensed 0.1 to 2000 Kilos of explosive
? Registered 0.1 to 30 Kilos of explosive
? Un licensed/Registered Up to 10 Kilo Black Powder,


though I am intrigued by the third category - does this indicate you don't need a licence for black powder - surely not!

In Topic: Castable rocket nozzle compositions

For the last month or so I've been making converging-divergin nozzles out of milliput putty and using an icing nozzle to form the cones.

I score a groove on hte inside of my tube,
put the milliput in and ram it slightly,
use a 2mm drill to put a pilot hole throug ht putty by hand then from each side press the piping nozzle into the milliput to make the cone shaped cavities. (put the nozzle on the end of a pencil to do the inside one)

I've reused hte tubes 3-4 times each and it seems to be the cardboard tube that burns away before the nozle erodes too much.

Erm long time ago and Organic wasn't my forte but I think on the second one, you use the base to promote production of a Carbanion as a starting point.

But it has been *cough* years since I saw an organic lab.

Eloquently put - but I'd agree, a very big pile.

A quick way of putting "feathers" on a stick would be to buy some rubber arrow fletchings and glue them on like you do to an arrow - not sure how many you'd need, but if you want an excuse to make loads ofrockets for experimental purposes I'm sure you could have fun wiht a long term experiment :)
