When you take a balloon filled with air to the bottom of a swimming pool, several physical principles come into play, primarily related to pressure and volume.

1. **Pressure Increase**: As you descend into the water, the pressure surrounding the balloon increases. The pressure in a fluid increases with depth due to the weight of the water above. For every 10 meters of water depth, the pressure increases by approximately 1 atmosphere (atm), which is about 101.3 kPa.

2. **Boyle's Law**: According to Boyle's Law, the volume of a gas is inversely proportional to the pressure exerted on it, provided the temperature remains constant. This can be expressed mathematically as:
   $$
   P_1 V_1 = P_2 V_2
   $$
   where $$P_1$$ and $$V_1$$ are the initial pressure and volume of the gas, and $$P_2$$ and $$V_2$$ are the pressure and volume at the new depth.

3. **Effect on the Balloon**: As you go deeper, the pressure on the balloon increases, which will cause the volume of the air inside the balloon to decrease. If the balloon is elastic, it will compress, and its size will reduce.

4. **Air Inside the Balloon**: The air inside the balloon will also be compressed due to the increased external pressure. If the balloon is taken to a significant depth, the volume of the air inside will be much smaller than it was at the surface.

5. **Potential Risks**: If the balloon is taken to a depth where the pressure is too high, there is a risk that the balloon could burst if it cannot withstand the external pressure. However, if the balloon is made of a strong material, it may simply compress without bursting.

In summary, as you take the balloon to the bottom of the swimming pool, the balloon will compress due to the increased water pressure, and the volume of air inside it will decrease according to Boyle's Law.
When you take the balloon to the bottom of the swimming pool, the increased water pressure will cause the balloon to compress, making the air inside it take up less space.
