Hundreds of students from the midlands are teaming up with Autism Ireland volunteers over two days to attempt a new world record by tweeting over one million times.

The students from Rochfortbridge in Co Westmeath have already started the Twitter record attempt from the air.

They tweeted while skydiving from 2,400 metres (8,000ft) above the Royal Canal in Co Longford.

Up to 500 students at Athlone Institute of Technology began the tweeting record attempt on the ground at their new International Indoor Athletics Arena.
