This type of novelty product is somewhat new to the UK market as manufacturers and importers continue to explore what’s possible under the current CE regulations that doesn’t fall foul of the “erratic flight” restriction.
Availability is still somewhat limited, with Trafalgar Group’s Crackling Balls and Spinning Saucers shown below as an example (RRP around £5 per pack). A firework brand called Klasek also produces similar items which are for sale from UK retailers.
