Sorry there are no yellow ones! I did not eat 'em!
Went back for a second go at this with some yellow ones in the right place, but my back could not stand the bending so too bad!! Used a syringe and needle to get my water drops where I want - just as well I don't work in hospital any more - gave myself several needle stick injuries - so blood and water..lol!!
Anyhow distances are critical and I am going to have to keep trying this (and eating the smarties!) to get it right.
