Former NASA and Apple engineer Mark Robert installed a bird feeder in his garden, but quickly noticed a problem: cunning local squirrels are stealing all the food from the birds. To solve it, Mark did not think of anything easier than creating an insane ninja warrior obstacle course for the squirrels.
However, he did not come to this decision immediately. First, he tried several different bird feeders with a system of protection against squirrels and each time he observed how they did not justify themselves in front of the tenacious paws of surprisingly smart rodents. This (and partly the boredom during the quarantine) inspired Mark to take further action.
The obstacle course turned out to be of good quality: it has a labyrinth, a rope bridge and even a catapult ... If the squirrel successfully passes the test, it is entitled to unhindered access to a huge pile of walnuts.
Incredibly, the squirrels here also found ways to cheat and disrupt the passage of the track, which forced Robert to redo and complicate the obstacles several times. During the passage of the strip, not a single squirrel was harmed! And to be convinced of this, we recommend watching the exciting video that Mark devoted to his experiment.
