Ziplock CO2 Grenade





Introduction: Ziplock CO2 Grenade

This is a design for a simple yet effective grenade. It uses vinegar and baking soda to make Co2 which pops the bag.

This is my first Instructable so I hope its alright.

Step 1: Materials Needed

you need, and seal wrap or similar(must be the sticky on one side stuff)
2.Snack size ziplock bag(you may use larger if you wish)
4.baking soda
5.Duct tape for sealing top of bag(optional)

Step 2: Baking Soda

Add some baking soda. You will need to experiment to find the right amount to add

Step 3: Press and Seal Wrap Bag

To keep the vinegar separate from the baking soda, you need to make a small bag out of the press and seal. To do this you need to fold a piece of wrap in half with the sticky side on the inside. Then seal the edge of the wrap to make a pocket that is open on top.

Step 4: Add the Vinegar

Pour the vinegar in to the press and seal bag and seal the top.

Step 5: Assemble the Grenade

Place the vinegar bag into the baking soda bag and close it.

Step 6: Detonate the Grenade

To detonate just squeze the grenade and then chuck it.

Step 7: Video

The video doesn't give it any justice. Usually there is a better delay and the pop sounds louder than it is in the video, but it gives you an idea.

    haha yeah its kinda pointless unlss u like make it with a garbage bag instead of a ziploc.... wait a minute

    heh, if you also put black pepper or lime juice or toothpaste or anything else that hurts ones eyes, you can wage chemical warfare!!!!! i am not liable for any injury to any object or person resulting from this comment

    How about some chilli powder?

    Chemical warfare? you say household angry backyard science warfare

     pretty much a water ballon

    Put it on the floor and you have a land mine!

    ...that asplodes 10 seconds after its pressed, and is really noticeabel. POUR SOME PAINT IN IT


    nice concept... Except that you should realy either hot glue or duct tape the bag close,hot glue works the best,and use a bigger bag , a lot more vinager [a cup of vinigar works best ,and alot of bakeing soda [use a cup to a cup and a half. good instructable though.
