Maximum Effort Jug

Materials:

1. Milk jug 
2. patterned Duck Tap
3. Rocks or sand
4. All purpose adhesive 

How to Make:

First, wash your milk jug out thoroughly. This may require you to add soap and shake and rinse repeatedly. This is important as nothing smells worse than sour milk in your classroom. After your milk jug is clean, you can begin to cover it with your patterned Duck tape. Covering it is optional but I feel this makes the jug more visually appealing. Finally, add some sand or rocks to the jug, and seal the top with adhesive. Make sure that it's not too heavy for your children to carry around.
