Strongest walls

We have recently been working on a mural designed by artist @d_a_n_e_ism at St.George Primary School on the Patmore Estate in Battersea.
What makes this wall different from most is that it uses a special paint called Graphenstone which contains Graphene, the hardest substance in science.
The wall actually absorbs CO2 from the air which is just what is needed especially in our heavy polluted City.
The mural features a Whale and is part of a series of pieces that Mr.Dane has been doing in the area.
Thanks to Patrick Foukes at Graphenstone for the support
