Yes, there are still five-days ahead of you before the weekend arrives, but it’s never too early to start planning your activities. For those who aren’t big on partying, continue reading to see five awesome gadgets you can make at home.
5. PVC Rocket
This video demonstrates how to fire a rocket under the power of a flammable aerosol. Hairspray or a flammable spray deodorant are the fuels of choice. The total cost of this project assuming the tools needed are already available is about $25. For that price you can make 4 rockets for the launcher, as the foam sleeping pad that they are made of is large enough to make multiples.
4. Fire Wire
This is an old trick done with fine steel wool to make a huge spiraling shower of sparks. Rapid oxidation of iron contained in the fine strands of steel is an exothermic reaction hot enough to provide the sparks. The process results in black iron oxide (Fe3O4) and red iron oxide (Fe2O3), which is more commonly known as rust. The carbon content found in steel adds to the brilliance of the sparks.
3. Sodium Metal
This is one way sodium metal can be isolated using NaOH and Mg. Mg has a strong enough desire for oxygen to tear it from the NaOH, leaving ingots of elemental sodium behind. 2Mg + 2NaOH = 2MgO + 2Na + H2.
2. Static Electricity Generator
In this video I show how to make a device that allows the user to gain the power of electricity. This high voltage generator can electrify a persons entire body with a static charge more powerful than rubbing even the softest footie pajamas on a carpet could ever muster. The electrical buildup can then be discharged with a touch to shock anything in reach.
1. Catapult Trap
This little catapult is fun to play with on its own, and even more fun to surprise friends co-workers with. A nice little device to stand guard in your doorway. Supplies needed: 1 Large Eraser; 3 Paper Clips; 1 Popsicle Stick; 1 Spring (this could be from a broken electronic device in the battery compartment); 1 Chapstick Cap; Hot Glue; Strong ScissorsPliers; String or Dental Floss for a Tripwire.
