    Paper Rocket

    Great, detailed explanation. Wonderful instructions. Stuffing the nose cone was a stroke of genius. Made slight modifications substituting thinner 2" packing tape instead of tacky painter's tape. Also changed up the small round insert for the top of the tube with a square piece of paper. I insert and fold over the tube/jig and then roll a sheet a paper over that. It's an assured seal. Instead of using the cut out for the body I use a full sheet of paper, any length in fact. Focus then is on just the fins and nose cone.BTW that jig you made, genius!!!

    Air Powered Rocket Launcher

    Great idea. Love the fact that kids can walk all over it without damaging it too much. And on behalf of Pack 785, we now have a great way to attract new scouts to our troop. Wonderful project!Just wanted to point out you could use 3/4" Nipples to join the solenoid valve to the body of the unit and the launch tube. They are found in irrigation. I used a simple strap and a 1"x2" piece of wood to secure the solenoid valve and keep it level with the rest of the body.To save on tape we use 2" packing tape to secure the body of the rocket and nose cone.We use the same 2" packing tape AND a square piece of paper on one end of the tube to ensure a consistent and air tight seal for launch. Only issue is the 9v battery life. With 3 batteries in series from my test i...

Only issue is the 9v battery life. With 3 batteries in series from my test it only lasted for a day (4 hours). That can get pretty expensive considering. Also to promote safety I added a "dad's" momentary switch to prevent premature launches in addition to the launch momentary switch. But I noticed that the line holds a residual charge. Any idea how to dissipate that? Not an EE and I thought a simple DC circuit would discharge. Any ideas?

    One thing they don’t tell you about solar power is the fact you will lose at least 30% of the power output due to transmission. Always plan for it.

  • Pro Tips for Using Cardboard

    Great article. Been in the packaging business for over 30 years. Been making prototype packaging for the past 15 years. A few things to add to what you've already created. 1. Folding cardboard is easy. All you need is a scoring tool to create a score. I use what looks like a spur attached to a handle. With a metal ruler run the scoring tool along the straight edge and viola you get a punched line that you can fold and create a nice crisp fold. (Also great for resizing a carton.) For paper board or card stock or index stock they have a similar tool which is a rolling knife with spaces in between. I also prefer to tuck the tongue inside to hide the cut side. 2. Get yourself one of those cutting mats. I like my 11x17 but you can get a nice 8.5 x 14 and it can still do the job ...

Get yourself one of those cutting mats. I like my 11x17 but you can get a nice 8.5 x 14 and it can still do the job well.3. Exacto knives are my friend. Easy to replace the blades and keep them sharp to prevent those rough cuts.4. Metal rulers are your friend. They keep nice straight unblemished edges and allow you to run your exacto knife along the edge easily. Plus those yardsticks are inexpensive enough. 5. Finally I prefer rubber cement. It allows me to fix mistakes and readjust board easily. The hot glue is a little more permanent for my needs.

  • Robotic Helmet That Stops You From Crying

    Stop crying. Give them a glass of water. Makes you look compassionate but you can’t drink and cry at the same time.
