Making LARP bombs
Hi! I'm new to this subreddit, I have played LARP for a couple of years, and I hope to find some help from you guys, surely more experienced than me.
I'm creating a new character for a medieval fantasy event called "Aston's crown" near Rome, in Italy, it's an alchemist goblin but I would like to build some bombs as well and I was wondering: how could I build a fake bomb? Maybe something interactive with sound but not too powerful of course. Is it possible to build a fake bomb which has sound or even just a visual effect but is still safe for others? Price range depends on how the bomb is, if it is a one time use I would prefer it to not be too expensive but I don't expect it to be like 2€ of course, if it is recoverable I can spend some money on it, let's say I can go up to 40/50€.
Thanks in advance for your help!
