This is a first for the UK. This type of product (ground mover) was previously disallowed in the UK, but due to recent changes and CE regulations they are now available. The hummer moves back and forth, ejecting it’s spare wheel before the doors open to reveal small humming spinners.
Please note that you will need a sold, flat area such as patio or driveway 8m square to use this firework. It will NOT work on surfaces such as grass, dirt, decking etc. Please also note that it is against the law to let fireworks off in a public place including roadway or path.
