The material of the balloon has pores- tiny holes too small to see without a microscope- but big enough to let air molecules slowly escape.

Air can escape from a balloon even when it is tied due to the gradual seepage of air molecules through the rubber material of the balloon. Over time, the pressure inside the balloon decreases as air leaks out, causing it to deflate.
A securely tied balloon will still deflate over time due to tiny holes in the material allowing air to escape through diffusion. On a warm day, the air inside the balloon expands and molecules move more quickly, causing the balloon to lose air quickly.
When a balloon is inflated but not tied at the end, releasing it causes the air inside to escape quickly, creating a force that propels the balloon forward. This is due to Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction.
When an air-filled balloon is left with its mouth downward and the air is allowed to escape, the balloon will collapse and shrink in size. This is because the air pressure inside the balloon is greater than the atmospheric pressure outside, causing the air to rush out until the pressures equalize.
When a balloon is popped with a nail, the air pressure inside the balloon rapidly decreases, causing the air to quickly escape. The sudden release of air creates a popping sound.
The air in a balloon can escape through small holes or tears in the balloon material, or when the balloon is intentionally deflated by releasing the air. When air is released from a balloon, it flows out due to the pressure difference between the inside and outside of the balloon.
