Coloured artillery shells that were on display at the Passchendaele Musuem. I'm not sure that these are their original colours, but I think they have been coloured for the display, which I thought was quite effective :)
@pennystot@kandkids@jamibann@dishaparekh176@365projectorgjenfurj thanks everyone. Yes I agree that at first they don't look like shells at all...and indeed they do like kinda pretty, which is hard to believe, considering they are designed to detonate nothing but destruction
