Ο Mark Rober διαθέτει ένα δημοφιλές κανάλι στο youtube, στο οποίο και έχει δοκιμάσει δεκάδες τρέλες θεωρίες στην πράξη. Αυτή τη φορά θέλησε να εξακριβώσει τι συμβαίνει με την κινούμενη άμμο.

Πώς θα το πετύχαινε αυτό; Συνέλαβε την ιδέα να γεμίσει μια πισίνα με orbeez. Τα πολύχρωμα αυτά μπαλάκια έχουν την ιδιότητα να απορροφούν μεγάλη ποσότητα νερού και να διογκώνονται. Ίσως τα έχετε δει σε γλάστρες, όπου χρησιμοποιούνται ως “αυτόματο πότισμα”, αφού συγκρατούν την υγρασία στο εσωτερικό τους και όταν υπερθερμαίνονται την αποβάλλουν.

Επί έξι ολόκληρους μήνες, συγκέντρωνε μαζί με τον Κέβιν, τον αποκαλούμενο και “επιστήμονα της πίσω αυλής”, τεράστιες ποσότητες από αυτές τις μπάλες και ήρθε η ώρα να δοκιμάσει τη θεωρία του. Δεδομένης της διαφορετικής πυκνότητας, πόσο θα βυθιστεί ένα ανθρώπινο σώμα σε μια τέτοια… πισίνα; Ως τα πόδια, μέχρι τη μέση ή μέχρι το λαιμό;
