My 8 year old got this yesterday for her birthday. It looked very promising. We just finished doing 3 of the experiments. There are 6 experiments total.
The first experiment we tried was the volcano. You need several standard kitchen items such as vinegar, baking soda, food coloring, and dish soap. Instructions say to place 2 teaspoons baking soda in the volcano top. Top holds 1 teaspoon max. Then you put the soap and food coloring in, and pour vinegar on top, resulting in the "eruption" which lasts a few seconds. The instructions provide an illustration showing how a real volcano works, sort of....
2nd experiment we did was another baking soda/vinegar based one which makes a rocket shoot up. We performed the steps exactly and said rocket kept "launching" in our hands, before we could put it on the ground.
3rd experiment was the fingerprints. This one was totally lame. You make your fingerprint on this black card, then dust it with cornstarch to make it appear (it sort of appears). We both tried this and, as recommended, wiped our finger on our noses to get oil on finger to make a better fingerprint on the first card. Then you put tape on the print and lift it off the card. Next you put the tape on the fingerprint record card where you supposedly can rub the print off the tape and onto the card and "observe" it, and check out the type of pattern your fingerprint has (swirl, whorls, etc.) We tried this several ties and it simply did NOT work. Let me point out we followed directions exactly and tried twice.
Oh well.
I would recommend searching on the internet for ways to do these types of experiments at home WITHOUT buying this typical made-in-China crappy kit.

I bought this for my six & eight year old grandchildren. We've done three of the "experiments" as I had the ingredients on hand.The volcano doesn't work per instructions as the called for baking soda is way too much. Once we adapted the baking soda we were able to create a goofy volcano that lasted about three seconds.
The fingerprint experiment didn't work at all.
The rocket experiment did work and the six year old enjoyed it. By this time the eight year was completely bored with the toy.
I'm not willing to spend 50 cents on a lemon to see if the other experiment works.
Certainly NOT worth the $10.00 I paid for it.
