Ebbinghaus Illusion

In the traditional presentation of the Ebbinghaus illusion, two central circles are of the same physical size appear to be different sizes as a result of the context circles surrounding them. Which central red circle looks larger?

I hope you answered that the one on the left looks larger, but what if I asked you to pick up each of the two central circles? Would your reaching movement betray a susceptibility to the illusion?
Actualy those both red circles in middle are in same size.
