A Tesla coil can produce dramatic high-voltage arcs, but those arcs are electrical discharges through air—not free-flying bolts of plasma. A coilgun, by contrast, accelerates a physical projectile. Because a Tesla coil can cause fatal electrocution, this is not a safe homemade build project.
What a Tesla coil can—and cannot—do
A Tesla coil is a high-voltage apparatus used to demonstrate electrical discharges and resonant energy transfer. In a University of Colorado Boulder teaching demonstration, a spark-gap Tesla coil produces arcs up to 75 cm and wirelessly lights a fluorescent tube. The display illustrates resonant energy transfer, electromagnetic fields and the breakdown of air into a conducting path.
That visible arc is not a plasma projectile traveling independently through space. It forms along an electrical discharge path; it does not behave like a bolt that can be aimed and fired as a weapon. The word “plasma” describes the ionized gas in the arc, not a self-contained payload.
Why a coilgun is a different device
A coilgun is an electromagnetic launcher, not a Tesla coil. A University of Central Florida senior design project describes a portable coilgun that launches ferromagnetic projectiles using electromagnetic acceleration. Its defining output is a physical object in motion, rather than an electrical arc in air.

| Device or concept | What it does | How it differs from a “plasma gun” |
|---|---|---|
| Tesla coil | Produces high-voltage arcs in a supervised educational demonstration. | Shows an electrical discharge; it does not launch a free-flying plasma bolt. |
| Coilgun | Uses electromagnetic acceleration to launch a ferromagnetic projectile. | Launches a physical projectile, not an arc. |
| Jacob’s ladder | Demonstrates high-voltage breakdown as an arc rises through air. | Shows plasma formation in an arc; it is not a directed projectile weapon. |
| Research plasma sanitization device | Investigated for treating fabric and sanitization. | Has a material-treatment purpose, not a weapon or Tesla-coil launcher purpose. |
Does any real device called a “plasma gun” exist?
The name appears in legitimate research outside the weapon idea. The University of Alabama in Huntsville describes research into a handheld plasma device for sanitizing fabric. The university says additional engineering work remains before the technology is ready for spaceflight. That research use does not establish a Tesla-coil weapon or a device that fires plasma at a target.
Why this is not a safe DIY project
The University of Colorado Boulder identifies its demonstration apparatus as operating at 8,000 V and 60 mA. Those are specifications for that university apparatus, not a build recipe or a general specification for Tesla coils. Its laboratory warning says, “This is not a toy; electrocution risk is real and potentially fatal.” The page compares the apparatus current with a 50 mA lethal-threshold figure; that comparison should not be treated as a universal line between safe and unsafe current.

- 💎【Magical Tesla Coil】:The magical Tesla coil generates high temperature and high pressure plasma, which can sing, wirelessly transmit electricity, light fluorescent lamps, and have wonderful arcs.
- ⚡【Supply voltage】:DC 15-24v, current 2A, DC5.5 interface/pin header
- 🎵【Audio input】: 3.5 Jack, can connect mobile phone, mp3, computer audio
- 🥇【Tesla's arc generation function】: After the power is turned on, the wire at the tail will generate an arc, which is beautiful.
- 🥈【Tesla lighting function in space】: After the Tesla coil is powered on, it can light up fluorescent lamps in space!
The same university warns of residual charge and shock at the power switch, overheating, electromagnetic interference with sensitive equipment and medical implants, loud discharges, and the danger of leaving the apparatus unattended. These risks are specific warnings for its teaching setup, not a complete safety standard. Do not use them as instructions for building or operating homemade high-voltage equipment. See the University of Colorado Boulder Tesla Coil demonstration and safety information and its Jacob’s Ladder demonstration.
If you want to see a Tesla coil or arc demonstration, choose a supervised demonstration at an educational institution rather than attempting to construct or handle a high-voltage device. A “Tesla coil educational kit” or “Tesla coil demonstration unit” describes an educational apparatus category; neither should be mistaken for a plasma gun or launcher.

- PCB DISCHARGE TIP & MULTI TIP DISCHARGE ★★★★★ When you use the PCB round discharge top, tesla coil will release 5 arcs from the round top. It has three discharge tips, any one of which is available. You can install one, two, or three. It can produce a maximum arc of 5.9 in (150 mm). THE PRODUCT CONTAINS MANUALS.
- AMAZING ★★★★★ Have you ever touched an arc? Do you feel pain? This is our most outstanding tesla coil. In normal mode, you can touch the arc slightly. If your fingers feel uncomfortable, you can retract your hand. It's amazing, you can tell anyone and share the joy with them. It can amaze everyone and is a very cool collectible and gift.
- HOW TO START RIGHT? ★★★★★ No grounding required, no instructions required, install secondary coil and discharge needle, plug in the power, turn on the switch and it will work. When installing the round top of PCB, only one discharge needle can be installed.
- MUSIC ARC MODE ★★★★★ Pay attention to. It can only play square wave music. When you turn on music mode, if there is no music playing, it will not produce arc. When you play the music, you will see the electric arc dance, very ornamental. Please turn the volume of the phone to the maximum so that the music mode can work normally.
- BLUETOOTH & TEMPERATURE CONTROL PROTECTION ★★★★★ You can connect to Bluetooth by searching the Bluetooth name (MH-M18 or XFW-M18) on your mobile phone. The Tesla coil includes temperature control protection. When the Tesla coil exceeds the specified temperature set by the component due to operation, it will stop working. It is necessary to turn off the power and cool down before it can work again. This effectively prevents Tesla coil from being damaged due to high temperatures.
