The 137 ton ‘Trembling Rock’ in France that almost ANYONE can push up and down

If you want to impress someone with a “tour de force” but you haven’t practiced, go to the commune of Huelgoat in France and ask someone to film you pushing the “Trembling Rock ” of 137 tons.

Yes, we said 137 tons.

The Trembling Rock is so named because if you push it in the right place, it wobbles back and forth – or “shakes”, as various amazing video clips demonstrate (if you look closely).

To go into a ball: Pictured is the 137-tonne ‘trembling rock’ in the commune of Huelgoat in France, so named because if you push it in the right place, it wobbles back and forth

The huge granite boulder has been attracting tourists to Huelgoat Forest for years.

One video shows a man successfully moving the boulder, which is seven meters (22 feet) in length, by simply pressing his back against one end.

Other videos demonstrate the strange phenomenon more clearly – in a second clip, the rock is seen going up and down easilydespite its enormous weight.

How is it possible? Dr Mark Whalley of the London-based society Institute of Physics (IOP) told MailOnline Travel it’s possible the ‘Trembling Rock’ is a ‘beautiful example’ of the ‘moments principle’.

A statement from the IOP explains: “Assuming that the rock rests on a relatively small area, one could think of it as two parts. Half is to the left of the pivot point and half to the right.

“Each side is effectively pulling down, wanting to spin the rock in that direction. The mass on each side of this pivot, however, is distributed in such a way that the effect of clockwise rotation balances the effect of counter-clockwise rotation.

“That’s what we live on a seesaw. Two people can sit [on] each end of a swing and it is perfectly balanced. All it takes is a slight push to move the set in one direction or the other. It is therefore possible that the Trembling Rock is a 137 ton granite swing.

However, according to the IOP, the rock should be examined to determine what makes it “shake”. “Without visiting the site and having the opportunity to test various ideas, it is not really possible to answer this question conclusively,” the statement added.

Trembling Rock isn’t the only unusual attraction among the beeches, oaks and chestnuts of Huelgoat’s 2,500-acre forest.

The forest, steeped in myth and legend, is linked to King Arthur, the hero of medieval tales who is said to have led the British defense against the Saxons in the 5th and 6th centuries.

According to Tourism Brittanythe locals claim that there is treasure hidden in the forest – the loot that was found by Arthur and Merlin the sorcerer.

Visitors can explore ‘Arthur’s Cave’ and ‘Arthur’s Camp’, a sequence of stones that was once a settlement. Some say the king was buried here.

Moreover, tradition has it that Gargantua the giant, created by the French Renaissance writer François Rabelais, once came to visit the forest of Huelgoat. The locals gave him a meal of broth, but it did not satisfy his appetite. Furious, he continues on his way, throwing stones at Huelgoat from afar.

At the “Maison de la Vierge”, visitors can identify rocks in the shape of a pot, a ladle, a fork, a bed and an umbrella.

This story adds to the mystery of the area’s unusual rock formations, which are around 340 million years old.
