Small clear round eggs?

After lifting my garden refuse bag, I found little clear eggs, just larger than half a centremetre in diameter. The eggs are slightly squishy, and feel rubbery to the touch.

Does anyone know what they could be? They are completely clear, with no sign of life. Maybe something will develop later?

Any ideas appreciated. I will keep an eye on them and hope the kids don't find them.
