Flying Saucer?

We have humming birds in the condominium's gardens so I wanted to attract them to our balcony.
Searched the pet shops here for a feeder but no luck, so I Googled how to make one.
What a palaver and not a bird came a calling, so I sent off to Amazon for one from America and here it is.
The solution is 1 part sugar and 4 parts water.
You dissolve the sugar in the water and bring to the boil, taking care not to make the solution too concentrated as the birds' internals are very sensitive and the incorrect solution can kill them.
...... hope they come along for a wee drink on the balcony.
