Not recommended!Arvosana 1/5
Very disappointed with this, which we bought as a gift to my son. Out of the 101 experiments, many are just trivial and extremely simple things, like brushing the head with a comb to create electrostatic charge, and others are very complicated to kids, with really poor instructions how to build it (just a picture from one angle), and sometimes difficult to make work, even for adults (and I am an engineer). The components seem taken directly from a component shop, not really crafted for kids. Overall, I feel very disappointed, my son as well, and I definitely cannot recommend this to anyone. I have seen better sets in internet.
