Each stool takes about 20 minutes to produce, using van der Wiel's machine that shapes the material according to the postion of magnets and the force of gravity.
Each one can be unique, dependending on where he places the magnets.
Van der Wiel graduated from the Gerrit Rietveld Academie in Amsterdam this summer.
Each day, for 30 days, a different designer will use a one metre by one metre space to exhibit their work at Dezeen Space.
