A cone fountain consists of a cardboard or heavy paper cone containing not more than how many grams of pyrotechnic composition?

• A. 75 g
• B. 50 g
• C. 100 g
• D. 25 g

Answer: (B)

The key idea here is safety-driven limits on how much pyrotechnic material a small device can contain. Cone fountains are compact, ground-based effects that burn quickly and shoot out sparks from a cone-shaped wrapper. To keep them as low-hazard devices suitable for routine handling and nearby audiences, regulators cap the amount of pyrotechnic composition inside the cone.

The maximum allowed for this type of device is fifty grams. This amount is enough to create a visible fountain without producing excessive heat, heavy smoke, or large debris, which helps keep risks within a controlled range and matches the handling and licensing expectations for small, cone-style effects.

Choosing larger amounts like seventy-five or one hundred grams would raise the energy released and hazards, moving the device into a higher-risk category. A smaller limit, such as twenty-five grams, would underdeliver the intended effect relative to the standard cone fountain design.

So, fifty grams is the correct upper limit for a cardboard or heavy paper cone fountain.
