Today i will show you how to make mini rockets out of the stuff you find in your house and only takes 10 minutes to make
Step 1: Materials and Tools
- tape (masking tape is probably best but duct tape would also work, but don't use clear plastic tape)
- paper (a normal piece of paper)
- a sparkler (or more if you want to make a larger rocket)
- a few matches
- pliers or something to remove the hardened powder from the sparkler and bend the wire
Step 2: Make the Tube
if you're going to use more than one sparkler make sure you roll a tube a lot longer than you need, half a centimetre in diameter
use masking tape to seal up the side of the tube and cut a bit of the two ends off, for neatness.
Step 3: Adding Fuel
fold one end the way shown in the images and seal with tape
now that the end is sealed, you can go ahead and put the sparkler powder in. i made a funnel out of a bit of paper, but you'd have to make sure the powder doesn't have chunks of unbroken bits of fuel so that it doesn't clog up
do make sure the powder is packed tightly and compact by pushing it down every centimetre of fuel you add
Step 4: Add a Fuse
you cut 2 cm off another sparkler, be careful here because the powder could crumble off the wire
once you've done that, put a piece of tape on the side of the tube, and press the fuse in as far in as it would go then stick the tape to it while it still has good contact with the fuel
now you should have the fuse stuck to the tube but enough room to add a little more fuel for extra chance of ignition. go ahead and add a bit of match heads or powder you spilt earlier so that it will ignite very well.
tape up the fuse side into a cone shape so no fuel falls out
everything should be secure, and now is the time for you to add another layer of tape for neatness, but it isn't the final layer
Step 5: Stability
we can do that by bending the wire like in the picture
bend a Z shape with the wire from the sparkler and on the short side, make a half loop at right angles to the wire, as shown in the image
attach the half loop to the tube, making sure that the fuse side is facing the wire, like in the picture, then slightly tighten it so that it is firm, but not so tight that the tube buckles
now that the wire is on the tube, you can tape over the wire. this is the final layer so make sure it's smooth
the last thing you need to do is to make sure the wire is directly under the tube so it flies straight. you can do this by carefully rotating the end of the wire and if the tube rotates without wobbling, its good. if it wobbles, the centre of gravity is not on the wire, and you need to bend it so it is.
make sure you don't grip too hard on the wire when rotating it because it is just going to bend and you'd have to straighten out the whole thing again.
