this is one i thought of one rainy day when i had an old recorder from elementary school (mean teachers made us buy them) and i decided to make somthing cool out of it. so i made somthing that shoots pointy thinks that hold food squirs skues somthing like that dont know) but it shoots them.
Step 1: What you need
2. strong tape
3. those pointy food thinks squirs skurs somthing like that
4. big rubber band
Step 2: Making the dart
cut it off with a dremel
now tape that end up so it does not cut the rubber band
there should be a pointy end i sanded it so it is very sharp i did that with a dremel.
make sure the dart is flat
Step 3: Makeing the gun
cut the rubber band so that it is not a loop
the bottom part of the recorder take the rubber band and put the middle of the rubber band there now pull both ends to the other side and tape them on there
(did not get a picture of that but it should look like the picture in the intro sry)
Step 4: What it can do
and dont worry if it does not shoot the way you want it to the first time try pulling the rubberband back further or closer but it is pritty cool once you get the hang of it.
