April Fools

In years past April Fools Day has come and gone without much fan fare.  But this year my big kids were really in the spirit of things (trying to play jokes on each other)  so I found a few ideas to play little pranks on them.
traded chips and resealed the bag with double stick tape

put Sprite in their water bottles. 
I think my son is going to be mad that I packed water for him.  I doubt he'll even open the bottle at school at all. 

bugs in the sammy
 Plastic glow in the dark bugs was the best I could find.  But I know my son will think it's funny.

I also filled their backpacks with small balloons and put plastic snakes on the table by their breakfast. 
I wonder how they are going to get even with me?  :)
Happy April everyone!
