Party Popper Canon
This is the grand-daddy of all party poppers, the party cannon. Instead of making a pathetic pop and releasing a few streamers, the party cannon goes with a whoosh and rockets out a massive payload of shredded paper.
The party cannon works by using compressed air, simply twist the base to let rip and send salvos of confetti up to 8 metres in the air.
You can get a pack of 4 from Firebox for £4.95 (each party cannon can only be used once (obviously)). Thanks to Healthspan Blog.com for the pointer. Be healthy longer.
