In the UK a trip to Lazerquest is a popular way to celebrate a birthday. It's a game where you shoot your friends with toy guns. Kids hide in dark corners and hope to surprise them.

Other people go bowling (打保龄球) and then have dinner at a nice restaurant. If it's your birthday you can choose whatever you want to eat and drink.

Going to an amusement park for your birthday is popular too. Amusement parks have big rides like roller coasters and ghost (鬼怪) trains. Parents often pay for their kids to bring some friends with them on these big days out.

If the weather is nice and you have enough space, you can have a garden party. People play games like blind man's bluff. One kid cannot see but has to try and catch the others by listening out for them. There's music at the party and sometimes a barbecue (烧烤野餐). Kids will usually bring along gifts like CDs or books to the party. Parents will buy their child a big present, like a game console (电子游戏机) or a bike.
