Eve is 8 and tonight she used a bit of food colouring to find out how many taste buds she has.

To do the same, all you need is some food colouring, a cotton bud, a key & a magnifying glass. Using the cotton bud, swab some food colouring onto the tip of your tongue. Then place the key on your tongue & count the pink dots within the keyhole. The pink dots are your fungiform papillae which house your taste buds & don't take up the food colouring. On average, non-tasters have less than 15 papillae in that area, while people who are 'super tasters' have over 30.

Thanks to Eve's Mum Siouxsie for helping with this experiment.
