The (tool-less) I-Spy Bottle

Step 5 Seal Bottle

Once it is all filled up, take about 1.5 ft of tape and just start wrapping it around the cap. This is to prevent kids from accidentally spilling oats everywhere. Once that tape is wrapped, tape the top twice with normal sized pieces of tape. Now take another 8 in. of tape and wrap it around the bottom of the cap so the tape is somewhat sealed to the bottle itself. In short, just tape it as much as possible with the strongest tape you have.
