You could try putting the eggs in a small pill container say 20 - 30ml.
Add some micro worms and about 1/2 full with water.
Put them in your pocket and carry on with whatever you were doing.
Check every 30mins or so for fry. Don't leave more than about 4 hrs, if still not hatching put back where they came from.
Worked for me, was the only way i got any scheeli out.
