Id on snail trail please

I keep finding these in my tank. I was wondering what it is. I know it comes from the type of snail that is pictured below. Thanx for your help!!!!

These appear to be eggs. This link might help. Look on the left collum and click the site info tab then on the left click the hitch hiker tab then scroll down to snails and look.
