Silver Polystrene Balls

Not sure. I did wonder about insulation. A neighbour has also found some in his garden but only a few. 
I’m pretty sure they aren’t packaging material. They’re bouncy and retain their shape.

Did someone have home insulation done near you recently? They are usually sprayed into cavities. Failing that it could be packaging protection.

Does anyone know what these silver polystyrene (?) balls are? They were covering my pond a couple of weeks ago. I thought it was someone throwing rubbish over the fence but they’ve turned up again!
