So it’s Halloween, and the trick and treater’s are out in force tonight. Sweets and chocolate seem to be the favourite ‘treat’ option, but when the kids trek home with a bucket full of candy, what to do with it all?!
Well, why not try out this quick and entertaining science experiment with your kids? It’s a great excuse to combine a bit of science fun with munching your way through all those sweets!
Take it in turns to try chewing a flavoured sweet while holding your nose – can you tell what flavour it is without looking at the wrapper? Let go of your nose and – voila! The flavour becomes apparent! Why not try it with different flavours to see if you can tell the difference?
This experiment neatly (and tastily!) demonstrates that smell and taste are very closely linked. Over 90% of what we think of as ‘taste’ is actually smell.
Want a healthy option to play this game? You can also try it with different fruit, although the distinctive textures can be a give away (a tip: telling the difference between apple and potato can be tricky!). We’d love to hear what other food you found this works with too!
Did you know? Our Personal DNA Portrait will reveal whether you have the gene for ‘bitter-tasting’ and as a result can taste the bitter compounds found in many green vegetables – a genetic reason for avoiding the Brussels Sprouts this Christmas. Yes, really!

Happy Hallowe’en everyone!
