Here is a list of instructions on how to make our water rocket



Step 1: Materials

Two 2 Liter bottles
garbage bag
tennis ball

Step 2: Step 1

Empty one 2 liter bottle and cut on 4 wings out of the cardboard (triangle shaped) to glue on the bottom of the bottle turned upside down (wings on the right, left, front, and back)

Step 3: Parachute

Get a large garbage bag and cut it into a circle. Attach 8 long strings (3 to 4 ft) evenly spaced out to the garbage bag. Then gather the 8 strings (NO TANGLED STRINGS) and tie a knot. Glue that knot to the top of the tennis ball.

Step 4: Second 2 liter bottle

Take the second 2 liter bottle and smooth out the bottle where to bumps are by using a hot plate and rotating the bottle over it. The bottle is pressurized. Once the bottle is smoothly rounded, cut the bottle in half and use the bottom half which is smoothly rounded

Step 5: Mini balloon

Blow up a mini balloon

Step 6: Putting it all together

Stand the base of the rocket (bottle with the wings) up, and then take the half rounded 2 liter bottle and put the balloon in it and then stuff the parachute along with the attached tennis ball in there as well. Take the rounded top and put it on top of the base of the rocket and lightly tape it together
