Step 1: Materials

-2 normal water bottles
-1 piece of paper
-baking powder or baking soda
-airsoft BB's
-vinegar

Step 2: Add Baking Powder

Take one of your water bottles and take you baking powder. Carefuly pour your baking powder into your FOLDED piece of paper. The baking powder should fall into you crease. Fill to about an inch from the bottom with baking powder. It should be about 1/6 of the way full.

Step 3: Add BB's

You should probably go with lighter BB's so they go faster when the grenade explodes. Put as many BB's as you want preferably about 20-40 BB's into the same piece of paper. Pour the BB's into the same bottle as the baking powder. Once you add them shake and mix in with baking powder.

Step 4: Add Vinegar

Fill up your second water bottle to the top with vinegar. When mixing ingredients only use 1/6 of the vinegar.

Step 5: Priming Grenade

Take your water bottles and QUICKLY combine the ingredients of both bottles into the bottle with the baking powder in it. QUICKLY put the cap on. You must shake a few times so an instant reaction dosn't occur.  Wait until the bottle is completely inflated then you will be able to hold it for a few minutes. When throwing throw with A LOT of force at the ground. The bottle will explode spraying BB's everywhere at your enemy. Have fun and play safe!      ALWAYS WEAR EYE PROTECTION! If you are using one of those "eco-friendly"  bottles, be careful
because it may explode in your hand only because the bottles use less plastic so when it inflates it will explode!!!!
