It is not fantacy.. it's real. human can climb wall

1. Z-Man
With this device, people could scale walls with ease

2. The Spider-Man fantasy
has finally been
realized, thanks to an
initiative of the Defense
Advanced Research
Projects Agency
(DARPA), the
Pentagon’s R&D
agency.

3. A new technology,
developed
by Cambridge
Massachusetts’
Draper Laboratory
under DARPA’s Z-
Man
initiative, allows a
person to climb a
flat surface using
two hand-held
devices.

4. The Department of Defense
calls the program Z-Man,
because — as DARPA
technology leader Eugene
Choi told Defense Tech in
2014 — “Spider-Man” was
already trademarked.

5. The initiative did study how
spiders walk on walls, but
researchers put most of their
focus on lizards, especially
the gecko — “one of the
champion climbers” in the
animal kingdom, as Z-Man
program manager Matt
Goodman said in a statement.

6. One of the first developments to come out of
this initiative was Geckskin.
Created by scientists at University of
Massachusetts Amherst in 2012,
Geckskin is a gecko-inspired adhesive that
can hold up to 660 pounds on smooth surfaces
and then easily release.
The secret of the material, and geckos’ feet, is
weakly attractive forces that bond one
molecule with a neighboring
molecule, allowing Geckskin to adhere
reversibly.

7. DAPRA demonstrated a paddle
that used Geckskin-like material
called MicroHold to allow a
human to climb a glass wall.

8. The new model combines the MicroHold
material with suction cups to allow for a
stronger adhesive in a smaller device that
can be easily carried on the battlefield.
Pistons attached to stirrups hang from
these two hand-held devices.
When the user steps down into the stirrups,
the pistons engage the suction cups and the
unit sticks to the wall.
Once the climber lifts their leg, the suction
releases.
Thanks to this mechanism, the device
requires no power to operate.
