It's simpler then it sounds to make a working bottle rocket and doesn't cost you much money. You only need a few materials. Getting the rocket assembled is easy..but getting the parachute to launch is a bit harder.   

Step 1: Get Materials

Two 2 litter soda bottles.
A Garbage bag or plastic bag (for the parachute)
Duct tape
Cardboard or foam core
A Tennis ball 
Dental floss or string

<p>how do u make the parachute stay to the bottle so the parachute can land on the ground safely?????</p>
<p>what does &quot;Then once the string is tied to the bag you cut a hole in the tennis ball so the string can fit through and get to the other side of the tennis ball. Then make a hole in the piece of cardboard or foam so the string can also get through. This will hold the tennis ball and string in place. Then tie the string so the tennis ball stays attached to the bag.&quot; mean? What piece of cardboard? What does the piece of cardboard look like? Do you mean one of the cardboard wings on the rocket? There was no instruction for the piece of cardboard that the strings pass through. What is the purpose of this piece of cardboard? Please be more clear if you are giving instructions.</p>

<br /> <br /> We have a sudden rash of water-rockets. I'm guessing it's a school project?<br /> <br /> Have you all seen the relevant groups:<br /> <br /> http://www.instructables.com/group/H2Orocketables/<br /> <br /> http://www.instructables.com/group/rockets/<br /> <br /> <br />
