Because the passageways in the toilet that carry the water from the tank to the bowl are, umm, 'full of air' (for lack of a better term). The water rushes from the tank into the bowl to flush, but all the air is in the way, so you see some come out of the siphon. That's as simple as I can make it.

Which one is the best flush available in Indian market for the air block problems?
A tank-style toilet with a siphon flush valve will likely do the job just fine.
How is a toilet sanitary?
A toilet maintains its sanitary condition by means of a water seal- -the clean water at the bottom of the bowl keeps odors away and bacteria at an acceptable level. The water stays in the bowl because a toilet has a trap like all other fixtures. The trap is visible on some toilets and the link below shows the basic design of the toilet. When water is released into the bowl (when the flush handle is activated) the water and all material in the bowl "overflow" out of the trap and create a siphon. The siphon pulls all of the water out of the bowl and then is broken when it sucks air (that gurgling sound after you flush.) Current law mandates the following conditions.1- Toilet must be made of smooth impervious material.2- Toilet must have acid resistant finish.3- Toilet must flush with 1.6 Gallons per flush or less.4- Toilet must have a non mechanical seal5- Toilet must evacuate at least 95% of the water (objectionable material) every flushhttp://www.homerepairforum.com/images/uploads/2005-9-10_Toilet_Bowl_FLUSH_STEP_1_w550.JPG
Why is there noise from the water tank in loft after flushing toiler?
I reckon there is no air vent pipe on the drain line of the toilet you are flushing and the siphon action is sucking out the water in the loft toilet also.
What is causing a Large air bubble when flushing toilet?
there are large air bubbles in your toilet because your pipes are to thin or are cloged deep into the pipe. if its clogged poor sour milk down your toilet and flush it will desolve what ever is cloging it
Why do all of these small air bubbles like an Alkaselzter tablet keep flowing into the toilet after I flush it?
Small air bubbles in the toilet after you flush could indicate a clog. The clog may not yet be big enough to stop the toilet from flushing but you should take care of it before it gets worse. You should get an auger to clear the clog.
Why when you flush a toilet on the main floor an air pocket comes into the bowl in the basement toilet?
This could be an indication of a blockage or you may need to install more venting lines.
Why would a bathtub not drain and when you flush the toilet air bubbles come up in the sink?
This is due to a blockage on your main sewer line, this is an indication that it may just be starting and getting it cleared asap will be beneficial to you.
Plumber problems the drain makes gurgling sounds when you flush the toilet and the water goes down in the toilet when the other toilet gets flushed?
either the vert is plugged and there is no air getting through or there is no vent at all
Is it true that when you flush your toilet it shoots into the air 7ft?
No, when the toilet flushs, it sucks everything in. It will then be calmly lead into the sea. Not shooted. In any way. Where the f*ck did you hear that anyway?
When flushed the toilet on the ground floor gives out a burst of air and then will not flush the water away how can this be fixed?
Install a proper vent
Iwant to install toilet in your workshop do you have to vent the pipe?
A toilet has to be vented otherwise you are trying to force liquid against the air in the drain and it is pulling against a vacuum. It will never flush right.
What does it mean when the toilets in a house won't flush properly - the water doesn't go out very quickly and they don't seem to empty correctly?
Here is a guess: The seal between the tank and the toilet is allowing air to seep in, thereby not allowing the momentum of the water in the tank to create the appropriate siphon effect. Change the rubber seal, or realign it.
