I have wrestled with - and split - absolutely loads of icing bags and plastic piping tubes over the years. These simple little 'squirty-pots' are really fun to use, and with good results. I've tried mashed potato, and this works well too. My old nozzles seem to fit as well which is a bonus! I thought that the problem would be when it came to the washing-up, but no worries there! They wash through easily and thoroughly. I would think that little people would enjoy using these in the kitchen as a great introduction to helping with the baking!
