Physical changes are exactly what is sounds like. You make a change of the item physically and it’s properties and name doesn’t change. E.g if you cut wood, it's still named a wood. You haven’t created diamonds or wood planks.

Chemical changes are the opposite of a physical change. You change the material chemically mostly creating another item mostly haves another scientific term for it. E.g you burn wood, it’s now classified as burnt wood and its irreversible.

Mysterious Phone Call

Nothing could prepare me for the next message that I found on my phone this morning.

This morning I received a dreadful and breathtaking text message from an anonymous entity that managed to get access friend’s phone named Durv. It said, “01010111 01100001 01101110 01101110 01100001 00100000 01101010 01101111 01101001 01101110 00100000 01101101 01111001 00100000 01100110 01110010 01100101 01100101 00100000 01100111 01101001 01100110 01110100 01100011 01100001 01110010 01100100 00100000 01100111 01101001 01110110 01100101 01100001 01110111 01100001 01111001” Which meant, “Wanna join my free giftcard giveaway” in binary. But it had a catch, Full of alien like font that means get a sacrificial subject and head to a particular sketchy place. Nowhere to be seen in Loogle maps. What made it more scarier today is 2017  and it was sent in 2069. “Does that mean aliens invaded the our terrestrial planet in the future?” I said to myself

I replied by saying with doubt and fear, “Sorry, but no thanks.” The out of this world entity and possibly an abomination said in full caps with tons of exclamation mark, “ H0W D4R3 Y0U!!!!!!!!!” The phone screeched with a distorted and unsatisfying sound. Me shrieking in fear immediately rushed outside killed one of my chicken and went to the living room.

I saw Durv drunk and unconscious from all the drinking. But dog paws foot steps found on top of the phone showing where the message were sent. “Hah, dumb dog. Although I killed this chicken for nothing, at least it’s nothing serious.” I went upstairs with relief and to the bathroom. I saw Keemstar our dog bleeding out! Me being a squeamish adult fainted in fear.

Gasp! “Ugh, I'm in bed? Guess it was just a bad dream.” I stood up and got my phone and saw the exact same messages. Then me being the curious George swiftly scurried downstairs to notice that Durv and the dog was dead!

To be continued!

Bubble inside a bubble?

As you know from my last explanation, a bubble contains air, detergent, air, detergent, air. This combination forms a levitating sphere like object that contains lots of variety of colours. But is it possible to blow a bubble inside a bubble? Let’s talk about that.

When blowing through a straw, you force air to penetrate into the solution (detergent) which then generates a pocket of air inside the newly formed bubble.  Then inner air pocket gradually tries push out. While the outer layer of the bubble the tries to push in, which is most likely caused by the common air outside the exterior of the bubble. Forming the elastic sphere shape.

Blowing individual bubbles inside each other is quite feasible. Due to the tension of air being pushed in and out. So once you blow your first bubble and blow your second one inside it. Both bubbles will expand in size due to the air you're forcing inside the interior. Making it eligible for more miniature bubbles to form inside the original one.

If you have successfully made lots of layers of bubble. It should look something like this.
