Free yourself from the tyranny of paper and boring 2D. With a $75 pen you can draw in thin air.
The 3Doodle pen, developed by US start-up WobbleWorks, works much like a handheld 3D printer. It contains a mains-powered heater that melts the plastic beads used in such printers.
You can draw normally using the colourful plastic as your ink – but with a fantastic twist. Lift the nib in the air and a length of plastic exudes from the nib and solidifies, allowing you to create 3D objects by building up multiple wispy strands of plastic.
Its just a hot-glue gun with plastic sticks inside(I think) instead of glue.
What I am thinking right now is that why didn't anyone come up with this for the consumer market earlier?
It sounds like a good consumer product.
They just need to find some way to make it edible with different flavors :P
