National Geographic Volcano Science Kit

The plaster needs better instructions. We oversized and it hardened and ruined our project. Also it would be nice if it came with a mixing bowl of some sort.

Kids (4 and 9) love this. We used extra rubber bands on the mold and it came out fine. Mix the plaster a little thicker and then add more water if needed. Our volcano has gone to 2 of our schools as part of science days. I’d buy it again.

This was a gift for a 7 year old, and he loved it.

Mold didn’t work - plaster dropped out everywhere. Had to throw away

Fun activity for my niece to do

It leaked everywhere! There was no way one rubber band would hold the three pieces together without cracks. The mold spilled out as soon as we put it in. Waste of money!

This was a Christmas present and my son was so excited for it. I made sure to read all directions so that there weren’t any problems. I poured the plaster into the volcano mold and it immediately started to pour from the sides of the mold, even with the rubber band in place. I adjusted the band but it continued to pour from the sides. My husband and I had to physically hold the sides closed while the plaster dried. The volcano ended up being half the size it should’ve because the plaster was wasted. It was such a disappointment because our family was so excited and this was the only activity we had planned on for the family activity.

Easy to follow instructions and easy to use. Great for school projects. My 9 yr old was thrilled! Dries quick and can be done in one evening together. She had the best volcano project in her science class!

Fun for both my 4 and 6 year old. Patience was practiced as we had to wait 2 hours as the plaster baked in the oven, but luckily it didn't take long before the paint dried and we were able to try out our volcano experiments. Fun bubbly reactions!

Perfect amount of fun in the box for our 7 year old

The mold is so terrible,literally leaked all out the bottom sides I had to break some hangers with the clips so I could clip the mold shut. What a waste cause now it isn't even a full volcano

Looks like fun, but it’s for Xmas ,so can’t really judge now.

Was not thrilled with the quality of this. All items are cheap and flimsy, hard to put together for myself let alone a child

The mold does not stay together, even with the rubber band. I recommend using super glue to glue the molds together because when we poured the mixture in, it leaked right out of the sides of the mold. Not worth it.

Since my child is under the 8 yr recommendation for this, I just had him watch. The instructions say not to breathe in the powder, but it poofs up such that I'd recommend wearing face masks, even when pouring carefully. Then, after at least two minutes of stirring, the mixture was still quite lumpy. A LOT pours out the side of the volcano mold & went through all the layers of newspaper to the floor we were working on. I don't have high hopes for the rest, since this part was not what I expected or what the instructions led me to believe.

Great Product! Kids loved it!!!!

This experiment was a hit in our housed

My 5 year old and 6 year old grandsons loved this! Fun and educational!

Great gift for my son who really enjoyed the process. He loved being able to build and paint the volcano and waiting for it to dry which created anticipation for the lava part and taught patience. Powder lava provided was enough for multiple uses. Great toy would recommend! Can be messy

It was a fun experiment to do with my son who’s 8 and infatuated with science. Easy directions, easy clean up.
