Rulers by Père Alex & Marchand de trucsThis classic illusion, made famous by psychologist Joseph Jastrow, is elegantly revisited here by Father Alex. The magician presents two wooden school rulers: one marked in centimeters, the other marked in inches. He explains that the imperial system is decidedly mysterious for a French person and immediately proves it: Placed side by side, 15 cm seem to be equal to 6 inches. By simply reversing the position of the rulers, not only do they visually
This classic illusion, made famous by psychologist Joseph Jastrow, is elegantly revisited here by Father Alex.The magician presents two wooden school rulers: one marked in centimeters, the other marked in inches.
He explains that the imperial system is decidedly mysterious for a French person... and immediately proves it:
Placed side by side, 15 cm seem to be equal to 6 inches.
By simply reversing the position of the rulers, not only do they visually change in size, but this time 7 inches appear to correspond to 9 cm.
To conclude, the magician reveals that the two rulers are in fact exactly the same length.
A strong, clear, and immediate visual illusion that never fails to surprise and delight.

Reliable protection that stays put during workouts!
Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
I’ve tried many expensive name-brand sunscreens, but this Amazon Basics version performs just as well, if not better. It’s become my go-to for morning runs and trips to the beach because it actually stays on even when I’m sweating.
Why I gave it 5 stars:
Non-Greasy Formula: Unlike other sport sunscreens, this one absorbs quickly and doesn't leave that heavy, sticky film on my skin.
Actually Water Resistant: I’ve used it for laps in the pool and long hikes; as long as I reapply as directed, I haven't had a single sunburn.
No "Sting": One of the best things is that it doesn't run into my eyes and sting when I start to sweat—a huge plus for runners.
Great Value: You get a generous 8-ounce bottle for a fraction of the price of "premium" brands. The fact that it’s formulated without Oxybenzone is an added bonus for peace of mind.
If you’re looking for effective, no-frills sun protection for an active lifestyle, you can't beat this. It’s a staple in my gym bag now!
