How do i convince my parents to let me get a trampoline?

Get a net around it, Then it won't be so dangerous.

Borrow the neighbours trampoline, and place it directly under the bedroom window. Then call your parents and siblings into the room. Take the youngest one, and push him/her out of the window, then when he/she bounces back up into view, a few times say ... "See Mom and Dad, Trampolines DO save lives." You'll be sure to win them over with that one. IF not, just save your money and buy one yourself. xoxo ♥

jump on their bed until they buy you one

Pay for it yourself.

♥ Offer to pay for half. If you don't have to money, just take a few babysitting jobs or something. ♥ If you say danger is the main issue, tell them that you can get it with safety nets. They really help, I would have fallen off a million times if it weren't for those nets. ♥ Promise not to do any flips of any kind. Sure, they're fun, but there is a ton of other fun stuff you can also do on the trampoline. Just be creative. ♥ If you buy a net and don't do flips, there really isn't a lot of danger. You can't fall off, you can't paralyze your neck. The worst that could probably happen is that you run into someone else and get a few bruises. ♥ Of course, there is still a small chance of something really bad happening. But you also take that chance when you walk, get in a car, fly, bike, etc....
