Are you referring to the fireworks?

Very much so, i have had the opportunity to work on 2 in my younger days. They are art on a completely different level.
Yeah the locals are crazy about fireworks. In summer every weekend one of the towns has it's "festa" with lots of fireworks / wheels.
You should visit Malta for the international fireworks festival in April, I'm sure there will be lots of firewheels ;) https://www.maltafireworksfestival.com/
