Materials

1 wide plastic lid (such as a lid from a margarine tub)
1 Drinking straw
Construction paper 
Kids' scissors 
A hole punch 
Crayons, markers, and/or stickers 
A small wad of play dough 

Instructions

1. Cut a triangle from a piece of construction paper - this will be your sail. 

2. Decorate the sail with crayons, markers, and/or stickers.

3. Punch three holes along one side of the triangle.

4. Weave a drinking straw (the boat's mast) through the holes.

5. Put a small wad of molding clay on the inside of the lid. Push the end of the drinking straw into the clay. 

6. You now have a cute little toy sailboat that can float in water!
