A bored teenager built a rollercoaster in his own back garden.

Logan Moore, 16, was inspired after spotting some disused wood and piping in his back yard.

The Kentucky schoolboy spent two months working on the one man wooden coaster over the summer break.

Logan - who wants to be an engineer - said he has even let his friends have a go and said the ride is 'a lot of fun'.

He built the ride completely by himself - putting in 15 hour days over his holidays to finish it.

The rollercoaster is pulled up to the tallest point on the ride - an 8.5ft hill - by a motorised winch connected to a car battery. Its top speed is 13mph.

Logan said: 'I took a class in carpentry class in school and I immediately fell in love with it.

'I have always loved to build things and always loved rollercoasters. I spend time researching them and looking them up on the internet.

Logan's mum Kathy added: 'I have to say tears filled my eyes when he finished the coaster'

'Over summer I saw some extra wood lying around. I started thinking about how it would work in my head and decided to build my own coaster.

'This is the second coaster I have built. The first one was smaller and I didn't like it so I tore it down and started again. I like this one a lot more.

'I have ridden it and it is really fun. My friends have also been on it and they think it's unbelievable.

'It was hard at some points. It's not like I wrote down exactly what I did. It was all in my head. And it was time consuming. But it really is amazing.'

Logan's mum Kathy added: 'I have to say tears filled my eyes when he finished the coaster.

'I was so proud and happy for him. His hard work and dedication to this has been amazing.

'Yes, I knew he was building it. One day he just told me he thought he would build a rollercoaster.

'I was shocked when I saw it starting to come together but Logan has always loved to build things and work outside.'
