Bouncy castles, also known as inflatable bounce houses, are designed to be anchored securely to the ground to prevent them from being blown away. However, it's important to take certain precautions to ensure the bouncy castle remains stable during use, especially in windy conditions. Here are some measures to help prevent a bouncy castle from being blown away:

1 Anchoring: Always follow the manufacturer's instructions for anchoring the bouncy castle properly. Most bouncy castles come with anchor points or straps that should be securely attached to the ground using stakes or sandbags.

2 Weighted Base: If you are setting up the bouncy castle on a hard surface like concrete or asphalt, use sandbags or weights on the corners or sides to provide additional stability. This helps counteract the upward force caused by wind.
