Bill Hammack, aka The Engineer Guy, is an amazing engineering educator and in this video he explains how duct tape is designed to simultaneously do three things well: “a) adhere with light pressure, b) stay in place, yet c) be removable”.
Controlling the stickiness of tape is of utmost importance. In fact, a key element of engineering tape is controlling its stickiness — and only by doing that can tape be wound into a useful roll. If the tape sticks too tightly to itself, we could not use it.
Gotta be honest: I was not expecting Silly Putty to make a relevant guest appearance during his explanation. And I love the ramp & ball test for tape stickiness near the end…a very elegant and simple bit of engineering:
Pressure sensitive tape predates much of the most elementary molecular understanding of adhesion; tape has been mass produced since the early twentieth century. That engineers developed and refined tape without this knowledge is no surprise — recall that the purpose of the engineering method is to solve problems before we have full scientific knowledge.

Galicia, Spain-based artist Abi Castillo continues to create iterative self-portraits through her evolving ensemble of ceramic personas. Her delicate yet emotive figures are an invitation to consider the inner self, transformation, and the beauty of the natural world.
Femininity, nature, and symbolism play a central role within Castillo’s sculptures, contrasting with the notion of concealment and ambiguity. “This ambivalence between mysticism and drama, between monstrosity and beauty, is all very present,” she explains in an artist statement.
Though each ceramic character is distinct, her body of work carries overarching formal motifs including colorful hairstyles and wide eyes with light blue irises. Organic elements—such as flowers, insects, coral, and marine foliage—wrap themselves around Castillo’s figures, evoking a sense of protection through delicate armor.
Last time we checked in with Castillo, she mentioned plans to move into a larger studio, where she works now. The artist shares that this opportunity has given her larger creative freedom, and she is looking forward to an exciting year including a group exhibition with Beautiful Bizarre Magazine opening next week at Outré Gallery in Melbourne. For updates and studio views, find Castillo on Instagram.

PEGEIA (ANP) - Schaker Anish Giri is er bij het Kandidatentoernooi op Cyprus niet in geslaagd voor de derde keer op rij te winnen. Na zeges op Rameshbabu Praggnanandhaa uit India en de Amerikaan Fabiano Caruana, moest de 31-jarige Nederlander donderdag in de tiende speelronde tegen de Amerikaan Hikaru Nakamura genoegen nemen met een remise.
Koploper Javokhir Sindarov won wel, van Praggnanandhaa. De Oezbeek vergrootte daarmee zijn voorsprong op nummer 2 Giri tot 2 punten. Na een rustdag op vrijdag volgt zaterdag de elfde speelronde.
De winnaar van het Kandidatentoernooi, dat duurt tot en met 16 april, strijdt om de wereldtitel tegen regerend kampioen Dommaraju Gukesh uit India.
