Smithsonian Volcano Kit
The Smithsonian Volcano Kit is designed for kids aged eight and up. It uses plaster of Paris, requiring a 24-hour curing time before painting and eruption. The kit includes cardboard pieces to form the volcano structure. While educational, the lengthy drying time might be a drawback for some.

The paint included seems insufficient for complete coverage, based on the reviewer's experience. More paint might be needed for a fully satisfying outcome. The build process is somewhat involved and might require adult supervision.

Discovery Kids Glowing Volcano Kit
The Discovery Kids Glowing Volcano Kit is comparable in size and build to the Smithsonian kit. It also utilizes plaster of Paris, demanding a 24-hour drying period. Similarly, the included paint quantity might not be enough for complete coverage.

The kit offers a glowing element, potentially increasing its appeal to children. However, the long drying time and potential paint shortage remain significant considerations.

Kids Labs Volcano Kit
The Kids Labs Volcano Kit uses a pre-made mold. After mixing and pouring plaster, it requires approximately 24 hours to dry. Once dried, the volcano is removed from the mold. This kit is smaller than others, measuring approximately 4 1/2 inches tall and wide.

The smaller size may be advantageous for younger children or those with limited space. While the drying time is similar to other plaster kits, the pre-made mold simplifies the construction process.

National Geographic & Ultimate Volcano Science Kits
The National Geographic and Ultimate Volcano Science kits are essentially identical, differing only in packaging. These kits also use a mold system, with a 24-hour drying period for the plaster. The construction process is straightforward, and the kits are reasonably priced.

The paint quantity and color selection seem adequate, though the reviewer didn't specify any significant issues. Overall, they represent a good value for a simple, yet effective, volcano kit.

Smooth Foam Mega Volcano Kit
The Smooth Foam Mega Volcano Kit stands out with its pre-assembled, three-piece design, eliminating the need for plaster and long drying times. It uses a water or soda bottle as an eruption chamber. The assembly is quick and easy, taking only seconds.

The kit provides ample paint, including charcoal gray and bright highlight colors. The large size and ease of assembly are major advantages. The eruption mechanism is effective and long-lasting due to the large chamber and bottleneck design.

Conclusion and Recommendations
Each volcano kit offers a unique experience, catering to different preferences and skill levels. The plaster kits (Smithsonian, Discovery Kids, Kids Labs, National Geographic/Ultimate) provide a more traditional build experience, but require patience due to the drying time and may have paint quantity limitations. The Smooth Foam Mega Volcano Kit stands out for its speed, simplicity, and superior paint provision. Its larger eruption chamber and bottleneck design result in a more impressive and longer-lasting eruption.

For those seeking a quick and easy project with a dramatic eruption, the Smooth Foam Mega Volcano is the clear winner. However, the plaster kits offer a more hands-on, crafting experience suitable for older children who enjoy longer projects. Consider the age, patience, and desired level of involvement when making your selection.
