Workbench has Gravity

so when the carpenter it making something and he puts something on there you see the wood just drop and be “eaten” by the workbench. i think it has to do with gravity coming into play not sure ill see if i can get a pic or something up if now give you 3 pictures. this 1 is hard to see but the carpenter is not holding anything besides the workbench

just finished making something and now is about to pick it up after effects of the workbench
