You get a load of fruits of different sizes that fit inside each other like russian dolls, and you carve them like pumpkins. They look really cute when they're all lined up, and it's a quick easy fun project that anyone can do.
Step 1: Procurement
Go to the supermarket and buy the fruit. We used, in order of descending size:
check the sizes, and try to get quite round fruit. e.g. rummage around for a -round- lemon.
Step 2: Gutting
cut all the fruit in half, and then gut it.
the citrus fruits are the hardest, because you need to leave enough skin on the inside to maintain structural integrity.
check they all fit - perfect!
Step 3: Facial Features
carve eyes in the top of each half. and a mouth into the bottom of each half. At this point, you should check the fit of the fruit inside each other again, so that you know that everything lines up.
we used a tim burton-esque style for the eyes, but you can do whatever you want.
Step 4: Spark 'em Up
to get the candle in the lime to stay lit, you need to make another airhole somewhere, and use a half a tea-light (shave the tea light's sides to reduce it's cross sectional area through the vertical axis).
