My granddaughter is 15 next week and has asked for a very unusual present. She wants to dissect a sheeps' heart! With this in mind, we've bought her some op theatre scrubs, mask, cap, gloves and scalpels and have ordered a sheeps' heart from the local butchers, who thought it was hilarious! She's so keen on Biology, she wants to do this at home whilst her mum videos it onto FB! Not quite the birthday present you'd expect to be asked for from a teenager!
