Party Cannons (Princes Risborough HP27)

Found these in the back of a cupboard. Not sure if they will work but don't think they have ever been 'fired'. You pull a tab and they release shiny paper and tissue maybe with a bang. Used to do a lot of fundraising for a charity and these were donated but never sold. Might be worth a try but please don't be disappointed if they don't work. You are welcome to take a look before deciding whether to take them.
