Trampolines provide a fun and popular pastime enjoyed by people of all ages. If you have a big enough garden (trampolines come in very small sizes to huge sizes) you can get a trampoline set up that you and your kids can use to have a great time. There are also trampoline clubs which are usually provided by a school or college for the use of their students, your kid might want to join if there is one at the school he is going to!
Trampolines are great fun and I love bouncing up and down on mine all day long!
