Typically, ground fireworks are designed to stay on the ground and produce a visual display using various effects, such as sparks and crackles. Aerial fireworks, on the other hand, are launched into the air and burst into a variety of colorful effects. You can usually identify whether a firework is ground or aerial by looking at its packaging or label. Ground fireworks are often labeled as fountains, spinners, or ground blooms, while aerial fireworks may be labeled as rockets, mortars, or shells. It's important to always read the label and follow the instructions for safe handling and use.
