EXPERIMENT Arc Welding vs Sparklers

This is sparklers. I have an thin and thick sparklers As you can see, they are very similar to welding electrodes So why not insert the sparkler into the holder and not burn it? Take first the thinner one It’s caught fire! You can use them like a normal electrode! OOPS! It ignited the other […]

How to make a mini Hydrogen Generator / TUTORIAL

您需要準備這些東西 2個同尺寸的冰棒棍 在棍面上畫上鑽孔點 再叧一根棍面上重做一次 再穩穩的將兩根冰棍壓緊 鑽孔 鑽孔後就像這樣 每相隔一個孔鎖上一個螺絲並穿過兩冰棍 再換面重做一次 再螺面上焊上錫點(可視螺絲材質選用合適的錫) 換面重做一次 然後 再螺面錫點上焊上電線 現在 可以將導電模組放入玻璃瓶中 瓶蓋上要鑽一個合適孔徑的洞 拿出西藥房買的滴管組 切掉上端 將電線穿過瓶蓋開孔 再將滴管組的觀察室塞進孔中,盡量塞緊 再用熱融膠封口,確保氣體不外洩 鎖緊瓶蓋 再依據實際需求剪截滴管 在集氣瓶鑽2個合適大小的孔 將滴管末端由孔1塞入瓶中 一定要將管子穿到瓶底 再將裁剩的那截滴管由孔2穿入瓶內.不必穿太深 再以熱融膠封口 這時 可以倒入清水了 蓋上瓶蓋 取一些鹽加水攪均 再打開瓶1 (導電模組) 倒入剛才自製的鹽水(導電液) 要淹滿整個導電模組 鎖緊瓶蓋 現在可以將電線接上電源供應器了 調整輸出電壓為 2.1 伏特 現在 您會看到瓶內開始有汽泡產生 (泡泡測試)

Young Worker Burned in Drum Explosion

A young worker was using a plasma cutting torch to cut the top off a 45-gallon drum. The “empty” drum had previously contained windshield washer concentrate. which was 100% methanol – a flammable liquid. Only about a tablespoon evaporated inside a drum is enough to be explosive. The torch pierced the drum. Vapours from residual […]

Workers Killed While Servicing Tires

I’m Olaf Knezevic, Engineer with WorkSafeBC. Tires can explode with devastating force, causing injury or death. I’m going to describe three serious tire accidents. In the first accident, a worker was killed while removing a tire from a log stacker. This stacker’s tires are mounted on rims made up of several pieces, including an inner […]

DANGEROUS 100W LED EXPLODES!

This is a very special and exciting device called a 100-W LED and I just bought it from an Ebay seller called happy fashion skirt. It cost $50 plus 10 cent shipping and according to their data sheet it’s the very latest power LED with 100 year life and it gives out 1 billion candle […]

Drum Explodes During Welding, Killing Worker

It doesn’t take much. Only about a tablespoon of acetone evaporated inside a 44-gallon drum creates enough vapour to make it explosive. At this kayak manufacturing shop, welding on an empty acetone drum cost a fibreglass worker his life. This is what happened. A worker wanted to make a shop cart from this empty acetone […]

Shipping Container Explodes, Injuring Worker

A full tank of propane can generate the same explosive force as over a hundred kilograms of TNT. Stored inside a shipping container, this tank became a bomb. Workers at a construction site used this barbecue during their morning break. Afterwards, the burner valves were turned off. In the afternoon the barbecue, with its tank […]

Exploding Acetylene Pumpkins! Halloween Science

Hi, it’s Halloween. We’re the Ri. So we’re exploding pumpkins. This year for our explosions we are going to be using this compound – calcium carbide. It reacts with water, fizzing away producing lots of gas and that gas is acetylene, which you may know is very flammable. We send the gas along the tube, […]

Master Welder

Oah, man what a boring day You’re safe now, stay here. You’ll be freed soon. Where am i supposed to go you asshole? Nooo, not again! Oh no, it’s the Master Welder Muhahahaha, I’m going to kill you slowly now I can do better It’s alright, you’re safe now The Hostages are secured, send in […]

EXPERIMENT Arc Welding vs Coca Cola

Hi everybody! Welcome to my backyard, and today I want to show you one crazy experiment! This is my welding machine, it can give a current of 200 amperes. So, let’s take it on and see what the welding mashine can do with Coca cola. Ooops! It’s unexpected! Look at this! Look! O! Man! The […]
