Super cool and if you wanted to take it a step further and add lights...... that would be sweet!
Step 1: Step 1 LAY OUT
THIS IS IMPORTANT!!! this is the layout for the next coupe of steps, so if you get confused,(which isn't hard to do), then refer back to this pic.
Step 2: Step 2: Building the Structure!
To make the ray gun, i used old parts that were in my junk drawer and modeled them to look like the ray gun. The only real requirement is the duct tape, and a toy gun. First take the Toy gun and a small wooden rod,( can be anything really), and fit it on the gun like showed on the pic.
Step 3: Step 3: Adding the Cardboard
When adding the cardboard you wanna make sure it makes the rod in the center front. But don't make it too big or it wont look good.
Step 4: Step 4: the Hockey Puck
I used a hockey puck to add on the back the potential "meter" that is on the side of the ray-gun. make sure it is pointing out because it is very important that there is a raise in the back.(refer to step 1 if confused). Trust me it may look terrible but it will come out looking awesome!!!
Step 5: Step 5: the Dome
now you want to take some cardboard and make the gun underneath visible. DONT MAKE IT TOO BULKY>or it will fall apart. Also make a small cardboard cut-out to put on the end to cover the interior.(look at the note on the pic)
Step 6: Step 6: Duct Tape
Duct Tape it so there isn't much showing and it looks like it has the shape of the ray-gun!
Step 7: Step 7: the Tube
Now add some sort of tube, (it doesn't need to be red my was just conveniently that way), tape AND/OR Glue <- Glue is the best way to go
Step 8: Your Ready for Spray Paint!!!!.
Spray paint everything but part of the top,( you will spray paint this light blue).
Step 9: Details: Meter
The meter, make a meter with green, yellow, and red and put some wire or draw a little meter pointer in one of the zones.Make it pop out of the rest of the gun. use hot glue
Step 10: Details: Switch
make a small switch next to the meter. (i just used a button and pin). use hot glue
Step 11: Details: the Grip
I painted a small part black and added small aluminum wires to make it look cool.
Step 12: The Nose: Corkscrew
At the end take a corkscrew and glue on end, take the metal wire and make the design that is displayed in the pic.
Step 13: Sight
make a sight like so and stick it where the pic shows! :D
Step 14: Final Decals
Make the decals on the picture.(on both sides). use metal wire and glue. also make small paper rectangles and put them on.
Step 15: WHHHHAAAAATTT *phew-phew*
