Can't get wow to work with wordpress

I'm trying to get wow js to work on my website but to no avail. The animations seem to trigger on page load rather than on page scroll.

The site is www.nothing-nowhere.co.uk

I've opened a stack overflow question (with all the details) and tried their responses but still nothing:

Can you spot what I'm missing

Thanks
