Just bury a trampoline with wide enough weave to let the roots of a hardy breed of grass grow into / mesh together with it when you cover it with sod. The kids could have a bouncy section of the lawn to play on.
If natural turf wears out too quick you could use Astroturf I guess. Anyway it wouldn't make your backyard look like hick central the way a trampoline does.-- doctorremulac3, Feb 09 2008 Would certainly make cutting the lawn much more interesting. Talk about putting a spring in your step...-- Canuck, Feb 09 2008 Darn, I thought this was going to be a security system that released over cafinated cattle to deal with trespassers, but I guess that would be a tramplelawn.-- MisterQED, Feb 09 2008 I thought that it could be like a Chia-trampoline but then I thought naw, sod it.-- 2 fries shy of a happy meal, Feb 09 2008 I can't believe how many of my neighbors are getting ugly trampolines. Why can't everyone chip in and get ONE and agree to let the neighbor kids use theirs? Seriously I live in a neighborhood with 1/4 acre yards, and at least 5 out of 12 in a row have them. Pretty ridiculous.
However, I assume families want their own kids in their own backyards to keep an eye on them, so a ground-level trampoline is a great idea. Even if the grass doesn't grow into it, having an in-ground trampoline similar to an in-ground pool sounds like an excellent solution to the eye-sores to me.-- paix120, Mar 29 2009 What I like about it is that nobody else knows that you have one. So in Quest's situation, the nerdy kid wouldn't discover 30 new friends lined up at his front door the next day.-- Jscotty, Mar 29 2009 One observation- You will still be able to fall off of it but your falling distance will be about 30-42 inches less with it being inground.-- Jscotty, Mar 29 2009 //I guess that would be a tramplelawn.//
I figured maybe a refuge for the homeless: tramp-o-lawn.
//But it still wouldn't bounce nearly as well as a traditional trampoline.// Unless you made it much bigger to compensate. It would be quite simple to turn the entire lawn into a square trampoline, with the centre part getting a huge amount of travel.-- mitxela, Mar 30 2009 Whoa. Moon Shoes. I'd forgotten all about that.
I just checked. They're still making them (making them again?). I wonder if they are as disappointing as they were 50 years ago.-- normzone, Mar 30 2009 If they bounced at the trampoline's resonant frequency though, even the tiniest jumps would build up to a ridiculous amplitude.-- mitxela, Mar 31 2009 random, halfbakery
