I will try to answer some of the previous points raised. Firstly regarding the maximum of 3kg of pyrotechnic composition in a cake. Not an unreasonable amount. Firstly it is important to remember that that amount is not ignited at one time and owing to the design, never will be, even if you threw it on a bonfire. If you had a 100 shot cake with 14mm tubes, each tube would have around 5 grams of gunpowder to launch the unit into the air. If it was a bombette unit (one that produces a starburst) 15 g of composition inside is not unreasonable. add 2g for a rising tail effect and 1g for the delay fuse, and we have a ballpark figure of 23g per tube. x 100 and we are up to 2.3kg. add about 20g for the time fuse that fires it and we are up to 2320g of composition. That much is required for it to function in 100 shots in a safe way to ensure it works correctly. As far as the comment about not being a vet is concerned, no, I am not. But the advice is passed on from qualified vets . There are many things that you can do to placate animals who are frightened, and I am not just talking about fireworks. Thunder storms can be frightening. Dogs in particular can have all sorts of things to help from sedative tablets, herbal sprays and the hug jacket that reassures them because it feels like they are being hugged by their owner. The argument about a product not being available is not always as clear cut as it would first seem. Many states in the USA and some other countries have more firework related accidents where they are banned, than when they are on sale, as people with little or no knowledge, mix highly dangerous chemical combinations together and cause injury or death to themselves and others. Handguns were banned in this country after the terrible events at Dunblane. So it follows that no handguns are ever used in a crime. Regulation is better than an underground that creates a black market for unregulated dangerous goods.
