Don't worry about it. Every year there is at least one person who has
never
seen these and is understandably concerned about them because they are
unknown. Nurseries use them quite a lot and we mix them into some
composts
as a 'standard issue'.

And I expect soon we'll get the inevitable 'What is this jelly like
substance on my lawn?' question from someone who's spilt the water retaining
crystals when they did their hanging baskets :-)
