May I draw the attention of the forum to pyrotooling.com, who are currently donating all proceeds from their BP rocket kits to the Fireworks Foundation's fight against the CPSC.

I would encourage all members to take the opportunity to buy these tools and support this important cause - where the US goes, the rest of the world follows... Shipping to the UK is only USD 12 for the 1lb kit - mine has just arrived.

I got pyro tools from China ,if anyone want just feel free to contact me .

Hey, it was me,the Chinese fireworks girl ,not he .I have registered this site , it is pretty cool. It seems many people are interested in fireworks.
