Titanium Volcano

Volcanoes usually spell disaster, but these little beauties spell an absolute bargain. For under four quid, you are getting a twin pack of high-performance fountains from Vulcan that punch well above their weight.

Each pack contains two units, one red and one blue base. Once lit, they erupt into a tall column of silver titanium flowers that can reach heights of 3 to 5 metres. With a total powder weight of 96g (that's nearly 50g per fountain), the duration is surprisingly long, giving you plenty of "oohs" and "aahs" for your money.

These are low noise, making them perfect for starting a display while the audience settles in, or for younger families who aren't keen on the loud bangs just yet.
