This tale is about young Ludvik (Robert Nespor) an erstwhile, budding scientist whose practical sense leads him to experiment before his common sense has figured out the results. Due to that unfortunate pattern, he variously floods the bathroom while working on displacement of volume and weight in water, he shatters the harvest pumpkins but not the law of gravity, and now he is eyeing the neighbor's rabbits for an electricity experiment. While the rabbits remain safe for awhile, Ludvik's parents wish he would follow in their more traditional footsteps and dedicate himself to music. Instead, Ludvik has learned that the proper mixture of a certain carbide and water can be explosive, and while he works on that technique, a friend tips off the physics teacher about these potentially disastrous plans.

Antonín Kachlík wanted to make committed films about the moral dilemmas of the working class, but in the era of normalisation, he could only proclaim how faltering individuals would eventually come to the desired thinking.

The children's detective story describes a thrilling and cheerful search for a lynx that someone stole from the zoo corner of the house of pioneers and young people (the creators apparently assume that large carnivores are commonly bred in the children's facility). However, the film is made completely ingeniously, the naïve plots hardly catch the eye. In one of the last roles, Vladimír Menšík will introduce himself as a police captain, leading a long-complicated investigation
