Oops! I think I broke Instructables!
The thread "...bigger than its belly can" has too many full stops in the title, which confuses computers, apparently.
I was just pointing out that, of all the engines you'd expect to see here, nobody has made a pulse jet engine. Yes, I made a jam jar version, but nobody has made a real one.
I don't know why, they're very easy (basically a big pipe with a fuel supply and no consideration for the neighbours).
Maybe you'd just like to buy one off ebay, or maybe you'd like to look at the pictures of the jet mounted on a scooter, imagine what the ride would be like, and tremble slightly in anticipatory panic...
I got a message from the seller:
I have a video of it doing approx 70mph down Croft start/finish straight,the moped has now gone as the plastic wheels did not last long !!.
