Lol this is not rocket science.
Python is attached to sink faucet and siphon head in tank.
Turn on faucet, siphon starts vacuuming water. Voila water draining from tank.
Reverse the knob at the bottom of the "Python No-Spill" that's attached to faucet and voila water now reversing and pouring into aquarium. (check temperature before doing so).
The idea of the Python is to avoid buckets or spillage associated with them.
