For our hidden compartment we got a gatorade bottle, put some dark food coloring and got a tube thats about 3 inches long and almost as wide as the top of the bottle. Then we took out enough of the gatorade to put the tube in without it over filling, and super glued all around the edges and top so that no gatorade would be able to get out. And put on the lid so it looks like a normal gatorade bottle.
Step 1: Step One: Get Darken Gatorade.
you must get a dark, almost black food coloring with a light colored gatorade so it mixes to get a dark, purpilish color.
Step 2: Step 2: Take Enough Gatorade Out So the Tube Wont Overflow the Bottle.
Step 3: Step Three: Fitting
You must make sure that the tube fits, without being too less or too much gatorade. Or it wont work right.
Step 4: Step 4: Super Glue
super glue around the edges of the gatorade bottle and tube to make sure gatorade cannot come out. Then glue the top part of the tube/ gatorade bottle.
Step 5: Step 5: Double Check
In order for this to work, you have to be able to tilt the bottle upside down and it not spill, and if it doesnt you didn't glue all of the tube/ gatorade.
Step 6: Step 6: Clean Up
If you think that the super glue looks too messy, when the super glue is completely dry and the gatorade doesn't spill, you can take the excess glue off, usually with your nails, so it will look more clean.
