Anyone for a zombie smoothie?

The first activity from the 'bumper book of summer' that took Little Miss's eye was potion making. We made frog juice (green and turns you into a frog), princess potion (makes you beautiful like a princess), fairy flying potion (no explanation needed) and our favourite, zombie smoothie. A sniff of this baby will turn you into a zombie apparently. Personally, I'm not risking it.....probably due to the mouldy scabs and worm poo in it!
