Zero Blaster Reviewed
Daniel Rutter writes "I've just reviewed the Zero Blaster, the smoke ring gun that ThinkGeek (among others) sell. It works. It's fun. It's a vortex ring physics demonstration with two triggers and a see-through mechanism. What more could you want for $20?" Thinkgeek and Slashdot are both owned by VA Software.
Do I really even have to answer that question?
Some possibilities:
Answer #1
Answer #2
Answer #3
My chemistry teacher bought this thing from thinkgeek because he was impressed by it. It doesn't shoot rings very far (a few centimeters really) and makes a horrible stink. Not as cool as you might think from the review and all the advertisements... :(
