flash powder Hoodie

Quite possibly the cheapest, most stable, most easily made and most easily acquired explosive that an average joe, wanting to blowing something up for the sake of fun, can make. Flash powder is commonly used in M80s, silver salutes, firecrackers, and cherry bombs as well as large scale salutes seen in professional fireworks shows. It consists of two components: finly powdered aluminum (2 micron), and potassium perchlorate mixed in a ratio of 3 parts aluminum to 7 parts potassium perchlorate by weight. Both of these components are perfectly legal to purchase, and can be purchased online by anyone, of any age, who has a credit card. The aluminum must be a very finly powdered flake style usually sold under the name indian black or german blackhead. It can be bought from eBay. The potassium perchlorate can be found at any number of internet suppliers. 1 pound of flash powder can be made for only around $20.00 US, although a typical device like an M80 contains only 5 grams (1 lb = 454 grams). The power of flash powder can be increased significantly by adding additives such as: sulfur, antimony sulfide or just simply black powder in small amounts, typically 8-9 parts flash powder to 1-2 parts additive. This however, decreases the stability and could cause spontaneous ignition especially if the additive is not free of acid. Flash powder is scientifically designated a low order explosive meaning it burns quickly producing a great deal of energy in a small about of time. Legally it is classified as a high explosive. Due to the ultra high burning temperature of aluminum the rate of burning in flash powder actually reaches the speed of sound causing a detonation like a high explosive. This requires a critical mass of 50 grams in order for the flame front to acheive the speed of sound. For this reason quantities of flash powder in excess of 50 g do not need to be confined within a container in order to explode.

Orderd a large hoodie about two years ago and the print in still holding up. I recently order a XL just do to the fact that the original has shrunk a little. The new hoodie is made with thicker material and fits perfect. I recommend ordering one size up.

bro my dog started barking when I wore this hoodie, he started talking in spanish and was like "Aiiiiii te ves sexy ¿Puedo conseguir tu número?" and then he did the stanky leg before he packed his bags and got 3 tickets to bikini bottom. I asked him who the other 2 people were and he told me "nah i just tryna sleep". Had to respect the dog, he got that dog in him. but yeah the hoodie was warm

Just amazing I started browsing on the urban dictionary for the best most exquisite word I could find. And lo and behold I found this! This word, or words fit so perfectly on the sweatshirt it to like it was made to be. The comfy and soft material truly hugs your body and makes you not want to get up Or do anything. 10/10

I LOVE THIS HOODIE!! It’s very comfortable, the writing seems like it’ll last for more than a few washes. Something to consider is embroidery! That’ll make your products stand out from just a regular hoodie with printings. Worth every dollar.

Would be South better to have the definition on it as well like we used to be able to customize tshirts, sweats or mugs especially at the higher prices…
