Milkshake straws are larger in diameter than soft drink straws. Since milkshakes are thick, they are very hard to drink with a small straw, thus the increased diameter of the straw makes it easier to drink.
Some creative ways to use a candy straw in a drink or dessert recipe include using it as a stirrer for a milkshake, using it as a garnish for a cocktail, or using it as a fun and edible straw for a smoothie or milkshake.

To enjoy a thick milkshake with a milkshake straw efficiently, try tilting the cup slightly and using a spoon to help scoop up the thick shake while sipping through the straw. This method allows you to enjoy the milkshake without struggling to get it through the straw.
You create a pressure difference in your mouth by lowering the air pressure inside when you inhale. This pressure difference causes the liquid to rise up the straw and into your mouth. The difference in pressure is what allows you to drink the liquid through the straw.
Through a straw. Like a plastic takeaway milkshake cup? With a lid over the top and a hole in the middle? They have those with straws in the hole but have to drink the whole container or put some sellotape over the end of a straw to block the exit.
Air pressure
As you suck on the straw air is removed from the inside of the straw and the air pressure within the straw is reduced. Once the straw's air pressure is reduced past atmospheric pressure of about 760 mmHg, the Patm forces the drink up the straw and into the sucker's mouth. Gases move from high to low pressure areas until equilibrium is reached.
The part of the milkshake that is in the upper portion of the straw is exposed to a warmer environment than the bottom of the straw. Since the bottom remains cold longer it continues to plug the lower end of the straw while the upper portion of milkshake begins to expand in volume as it thaws. Since the bottom is plugged and the capacity of the straw remains constant, the increased volume of fluid spills out of the top of the straw.
Because you suck it up
When you suck on the straw, the pressure inside your mouth is less than the outside air pressure. Because of the imbalance, the outside pressure pushes the milkshake down the glass, up the straw and into your mouth.
The difference between hay and straw as mulch lies in straw being cleaner and having fewer seeds in general and fewer weed seeds in particular.
When you suck on a straw, you create a vacuum in your mouth, and the atmospheric pressure pushes the liquid up the straw and into your mouth. The difference in pressure between the area inside the straw and outside is what causes the liquid to move upwards.
