The Dutch go nuts with fireworks on New Year’s Eve, and so do I. This was my second year to throw a fireworks party in my 3rd floor flat here in Amsterdam. We set off firecrackers, rockets, etc., with flashbulbs and a dynamite plunger. It’s marginally safer and more fun than just chucking fireworks out the window. And it’s LEGAL.
Link. Do not (neccessarily) try this at home, possums. A lot of things are legal in Amsterdam, elsewhere YMMV. And not everything that’s legal is good for your health, or that of your houseguests or furniture.
