Can't Un-Ziplock: Hungry April fools will be trying hard to wrestle the goods out of one of these special sandwich bags. The reason? The opening is discreetly sealed with a thin line of clear adhesive strip. To set up the prank, zip the bag closed and place a length of double-sided scrapbook tape (we used Zips Ultra Thin Clear Adhesive Lines) on one of the flaps just above the closure. Firmly press the flaps together to make them stick.

Wormy Apple: The creature wiggling out of this apple will make an April Fools' Day lunch both silly and sweet. Use a plastic ballpoint pen, washed and with the ink cartridge removed, to bore a hole in the fruit, then insert a gummy worm. (Don't make it the night before, or the worm may get mushy.)

Snack Switcheroo: The joke in this snack-sized scheme is let out of the bag as soon as your target realizes the contents don't match the label. Make the switch by carefully opening a snack bag along the top seam. Empty out the original contents and fill the bag with another edible item (we filled a cheese puff bag with baby carrots). Add a playful message such as "April Fools!," then use a strip of double-sided tape to reseal the bag along the seam.
